Deuteronomy 27:10

there shalt thou build an altar . . . of whole stones--The stones were to be in their natural state, as if a chisel would communicate pollution to them. The stony pile was to be so large as to contain all the conditions of the covenant, so elevated as to be visible to the whole congregation of Israel; and the religious ceremonial performed on the occasion was to consist: first, of the elementary worship needed for sinful men; and secondly, of the peace offerings, or lively, social feasts, that were suited to the happy people whose God was the Lord. There were thus, the law which condemned, and the typical expiation--the two great principles of revealed religion.

Here is, I. A general charge to the people to keep God's commandments; for in vain did they know them, unless they would do them. This is pressed upon them, 1. With all authority. Moses with the elders of Israel, the rulers of each tribe (Deu 27:1), and again, Moses and the priests the Levites (Deu 27:9); so that the charge is given by Moses who was king in Jeshurun, and by their lords, both spiritual and temporal, in concurrence with him. Lest they should think that it was Moses only, an old and dying man, that made such ado about religion, or the priests and Levites only, whose trade it was to attend religion and who had their maintenance out of it, the elders of Israel, whom God had placed in honour and power over them, and who were men of business in the world and likely to be so long so when Moses was gone, they commanded their people to keep God's law. Moses, having put some of his honour upon them, joins them in commission with himself, in giving this charge, as Paul sometimes in his epistles joins with himself Silvanus and Timotheus. Note, All that have any interest in others, or power over them, should use it for the support and furtherance of religion among them. Though the supreme power of a nation provide ever so good laws for this purpose, if inferior magistrates in their places, and ministers in theirs, and masters of families in theirs, do not execute their offices, it will all be to little effect. 2. With all importunity. They press it upon them with the utmost earnestness (Deu 27:9, Deu 27:10): Take heed and hearken, O Israel. It is a thing that requires and deserves the highest degree of caution and attention. They tell them of their privilege and honour: "This day thou hast become the people of the Lord thy God, the Lord having avouched thee to be his own, and being now about to put thee in possession of Canaan which he had long promised as thy God (Gen 17:7, Gen 17:8), and which if he had failed to do in due time, he would have been ashamed to be called thy God, Heb 11:16. Now thou art more than ever his people, therefore obey his voice." Privileges should be improved as engagements to duty. Should not a people be ruled by their God?
II. A particular direction to them with great solemnity to register the words of this law, as soon as they came into Canaan. It was to be done but once, and at their entrance into the land of promise, in token of their taking possession of it under the several provisos and conditions contained in this law. There was a solemn ratification of the covenant between God and Israel at Mount Sinai, when an altar was erected, with twelve pillars, and the book of the covenant was produced, Exo 24:4. That which is here appointed is a somewhat similar solemnity.
1. They must set up a monument on which they must write the words of this law. (1.) The monument itself was to be very mean, only rough unhewn stone plastered over; not polished marble or alabaster, nor brass tables, but common plaster upon stone, Deu 27:2. The command is repeated (Deu 27:4), and orders are given that it be written, not very finely, to be admired by the curious, but very plainly, that he who runs may read it, Hab 2:2. The word of God needs not to be set off by the art of man, nor embellished with the enticing words of man's wisdom. But, (2.) The inscription was to be very great: All the words of this law, Deu 27:3, and again, Deu 27:8. Some understand it only of the covenant between God and Israel, mentioned Deu 26:17, Deu 26:18. Let this help be set up for a witness, like that memorial of the covenant between Laban and Jacob, which was nothing but a heap of stones thrown hastily together, upon which they did eat together in token of friendship (Gen 31:46, Gen 31:47), and that stone which Joshua set up, Jos 24:26. Others think that the curses of the covenant in this chapter were written upon this monument, the rather because it was set up in Mount Ebal, Deu 27:4. Others think that the whole book of Deuteronomy was written upon this monument, or at least the statutes and judgments from ch. 12 to the end of ch. 26. And it is not improbable that the heap might be so large as, taking in all the sides of it, to contain so copious an inscription, unless we will suppose (as some do) that the ten commandments only were here written, as an authentic copy of the close rolls which were laid up in the ark. They must write this when they had gone into Canaan, and yet Moses says (Deu 27:3), "Write it that thou mayest go in," that is, "that thou mayest go in with comfort, and assurance of success and settlement, otherwise it were well for thee not to go in at all. Write it as the conditions of thy entry, and own that thou comest in upon these terms and no other: since Canaan is given by promise, it must be held by obedience."
2. They must also set up an altar. By the words of the law which were written upon the plaster, God spoke to them; by the altar, and the sacrifices offered upon it, they spoke to God; and thus was communion kept up between them and God. The word and prayer must go together. Though they might not, of their own heads, set up any altar besides that at the tabernacle, yet, but the appointment of God, they might upon a special occasion. Elijah built a temporary altar of twelve unhewn stones, similar to this, when he brought Israel back to the covenant which was now made, Kg1 18:31, Kg1 18:32. Now, (1.) This altar must be made of such stones as they found ready upon the field, not newly cut out of the rock, much less squared artificially: Thou shalt not lift up any iron tool upon them, Deu 27:5. Christ, our altar, is a stone cut out of the mountain without hands (Dan 2:34, Dan 2:35), and therefore refused by the builders, as having no form or comeliness, but accepted of God the Father, and made the head of the corner. (2.) Burnt-offerings and peace-offerings must be offered upon this altar (Deu 27:6, Deu 27:7), that by them they might give glory to God and obtain favour. Where the law was written, an altar was set up close by it, to signify that we could not look with any comfort upon the law, being conscious to ourselves of the violation of it, if it were not for the great sacrifice by which atonement is made for sin; and the altar was set up on Mount Ebal, the mount on which those tribes stood that said Amen to the curses, to intimate that through Christ we are redeemed from the curse of the law. In the Old Testament the words of the law are written, with the curse annexed, which would fill us with horror and amazement if we had not in the New Testament (which is bound up with it) an altar erected close by it, which gives us everlasting consolation. (3.) They must eat there, and rejoice before the Lord their God, Deu 27:7. This signified, [1.] The consent they gave to the covenant; for the parties to a covenant ratified the covenant by feasting together. They were partakers of the altar, which was God's table, as his servants and tenants, and such they acknowledged themselves, and, being put in possession of this good land, bound themselves to pay the rent and to do the services reserved by the royal grant. [2.] The comfort they took in the covenant; they had reason to rejoice in the law, when they had an altar, a remedial law, so near it. It was a great favour to them, and a token for good, that God gave them his statutes; and that they were owned as the people of God, and the children of the promise, was what they had reason to rejoice in, though, when this solemnity was to be performed, they were not put in full possession of Canaan; but God has spoken in his holiness, and then I will rejoice, Gilead is mine, Manasseh is mine; all my own.

Deuteronomy 27:9, 10

9. And Moses, and the priests the Levites, spake unto all Israel, saying, Take heed, and hearken, O Israel; This day thou art become the people of the Lord thy God.

9. Et loquutus est Moses et sacerdotes Levitae ad omnem Israel, dicendo, Ausculta et audi Israel, hodie factus es in populum Jehovae Deo tuo.

10. Thou shalt therefore obey the voice of the Lord thy God, and do his commandments and his statutes, which I command thee this day.

10. Audias ergo vocem Dei tui, et facias praecepta ejus, et statuta ejus quae ego praecipio tibi hodie.

The ground of his exhortation is again taken from the special favor of adoption, wherewith the God of Abraham had honored them; for there was nothing which should have more effectually stimulated them to obedience, than that more than paternal love, and the gratuitous kindness with which He had prevented them. Although, at the same time, they were admonished in these words of the object for which they were separated from other nations; for the conclusion he draws is, that because they were received by God as His people, they, therefore, lay under an obligation to keep His statutes; as Paul more plainly teaches us that we are redeemed from all iniquity, that Christ might purify unto himself a peculiar people, zealous of good works. (Titus 2:14.) Moreover, since the priests were now appointed, from whose lips the doctrine of the law was to be sought, they here come forward in God's own name, and engage the people to respond to His generous calls upon them; and not only this, but also to obey His ministers.

Thou shalt therefore obey the voice of the Lord thy God,.... In whatsoever he directs in his word, and by his prophets, and especially by his Son, eminently called the Word of the Lord:

and do his commandments and his statutes, which I command thee this day; See Gill on Deuteronomy 27:1.

The command in Deu 27:1 to keep the whole law (שׁמר, inf. abs. for the imperative, as in Exo 13:3, etc.), with which the instructions that follow are introduced, indicates at the very outset the purpose for which the law written upon stones was to be set up in Canaan, namely, as a public testimony that the Israelites who were entering into Canaan possessed in the law their rule and source of life. The command itself is given by Moses, together with the elders, because the latter had to see to the execution of it after Moses' death; on the other hand, the priests are mentioned along with Moses in Deu 27:9, because it was their special duty to superintend the fulfilment of the commands of God.
Deu 27:1-3
Deu 27:2 and Deu 27:3 contain the general instructions; Deu 27:4-8, more minute details. In the appointment of the time, "on the day when ye shall pass over Jordan into the land," etc., the word "day" must not be pressed, but is to be understood in a broader sense, as signifying the time when Israel should have entered the land and taken possession of it. The stones to be set up were to be covered with lime, or gypsum (whether sid signifies lime or gypsum cannot be determined), and all the words of the law were to be written upon them. The writing, therefore, was not to be cut into the stones and then covered with lime (as J. D. Mich., Ros.), but to be inscribed upon the plaistered stones, as was the custom in Egypt, where the walls of buildings, and even monumental stones, which they were about to paint with figures and hieroglyphics, were first of all covered with a coating of lime or gypsum, and then the figures painted upon this (see the testimonies of Minutoli, Heeren, Prokesch in Hengstenberg's Dissertations, i. 433, and Egypt and the Books of Moses, p. 90). The object of this writing was not to hand down the law in this manner to posterity without alteration, but, as has already been stated, simply to set forth a public acknowledgement of the law on the part of the people, first of all for the sake of the generation which took possession of the land, and for posterity, only so far as this act was recorded in the book of Joshua and thus transmitted to future generations.
Deu 27:3
Upon the stones there were to be written "all the words of this law:" obviously, therefore, not only the blessings and curses in Deu 27:15-26 (as Josephus, Ant. iv. 8, 44, Masius, Clericus, and others maintain), nor only Deuteronomy (J. Gerhard, A. Osiander, Vater, etc.), since this contained no independent "second law," but the whole of the Mosaic law; not, indeed, the entire Pentateuch, with its historical narratives, its geographical, ethnographical, and other notices, but simply the legal part of it - the commandments, statutes, and rights of the Thorah. But whether all the 613 commandments contained in the Pentateuch, according to the Jewish reckoning (vid., Bertheau, die 7 Gruppen Mos. Ges. p. 12), or only the quintessence of them, with the omission of the numerous repetitions of different commands, cannot be decided, and is of no importance to the matter in hand. The object aimed at would be attained by writing the essential kernel of the whole law; though the possibility of all the commandments being written, of course without the reasons and exhortations connected with them, cannot be denied, since it is not stated how many stones were set up, but simply that large stones were to be taken, which would therefore contain a great deal. In the clause, "that thou mayest come into the land which Jehovah thy God giveth thee," etc., the coming involves the permanent possession of the land. Not only the treading or conquest of Canaan, but the maintenance of the conquered land as a permanent hereditary possession, was promised to Israel; but it would only permanently rejoice in the fulfilment of this promise, if it set up the law of its God in the land, and observed it.
Deu 27:4-8
In the further expansion of this command, Moses first of all fixes the place where the stones were to be set up, namely, upon Mount Ebal (see at Deu 11:29), - not upon Gerizim, according to the reading of the Samaritan Pentateuch; for since the discussion of the question by Verschuir (dissertt. phil. exeg. diss. 3) and Gesenius (de Pent. Samar. p. 61), it may be regarded as an established fact, that this reading is an arbitrary alteration. The following clause, "thou shalt plaister," etc., is a repetition in the earliest form of historical writing among the Hebrews. To this there are appended in Deu 27:5-7 the new and further instructions, that an altar was to be built upon Ebal, and burnt-offerings and slain-offerings to be sacrificed upon it. The notion that this altar was to be built of the stones with the law written upon them, or even with a portion of them, needs no refutation, as it has not the slightest support in the words of the text. For according to these the altar was to be built of unhewn stones (therefore not of the stones covered with cement), in obedience to the law in Exo 20:22 (see the exposition of this passage, where the reason for this is discussed). The spot selected for the setting up of the stones with the law written upon it, as well as for the altar and the offering of sacrifice, was Ebal, the mountain upon which the curses were to be proclaimed; not Gerizim, which was appointed for the publication of the blessings, for the very same reason for which only the curses to be proclaimed are given in Deu 27:14. and not the blessings, - not, as Schultz supposes, because the law in connection with the curse speaks more forcibly to sinful man than in connection with the blessing, or because the curse, which manifests itself on every hand in human life, sounds more credible than the promise; but, as the Berleburger Bible expresses it, "to show how the law and economy of the Old Testament would denounce the curse which rests upon the whole human race because of sin, to awaken a desire for the Messiah, who was to take away the curse and bring the true blessing instead." For however remote the allusion to the Messiah may be here, the truth is unquestionably pointed out in these instructions, that the law primarily and chiefly brings a curse upon man because of the sinfulness of his nature, as Moses himself announces to the people in Deu 31:16-17. And for this very reason the book of the law was to be laid by the side of the ark of the covenant as a "testimony against Israel" (Deu 31:26). But the altar was built for the offering of sacrifices, to mould and consecrate the setting up of the law upon the stones into a renewal of the covenant. In the burnt-offerings Israel gave itself up to the Lord with all its life and labour, and in the sacrificial meal it entered into the enjoyment of the blessings of divine grace, to taste of the blessedness of vital communion with its God. By connecting the sacrificial ceremony with the setting up of the law, Israel gave a practical testimony to the fact that its life and blessedness were founded upon its observance of the law. The sacrifices and the sacrificial meal have the same signification here as at the conclusion of the covenant at Sinai (Exo 24:11). - In Deu 27:8 the writing of the law upon the stones is commanded once more, and the further injunction is added, "very plainly." - The writing of the law is mentioned last, as being the most important, and not because it was to take place after the sacrificial ceremony. The different instructions are arranged according to their character, and not in chronological order.
Deu 27:9-10
The words of Moses which follow in Deu 27:9 and Deu 27:10, "Be silent, and hearken, O Israel; To-day thou hast become the people of the Lord thy God," show the significance of the act enjoined; although primarily they simply summon the Israelites to listen attentively to the still further commands. When Israel renewed the covenant with the Lord, by solemnly setting up the law in Canaan, it became thereby the nation of God, and bound itself, at the same time, to hearken to the voice of the Lord and keep His commandments, as it had already done (cf. Deu 26:17-18).
