Deuteronomy 22:11

Keeping wool and linen separate showed Israel's separation as God's holy people (see also Leviticus 19:19).

thou shalt not wear a garment of divers sorts--The essence of the crime (Zep 1:8) consisted, not in wearing a woollen and a linen robe, but in the two stuffs being woven together, according to a favorite superstition of ancient idolaters (see on Lev 19:19).

Here are several laws in these verses which seem to stoop very low, and to take cognizance of things mean and minute. Men's laws commonly do not so: De minimis non curat lex - The law takes no cognizance of little things; but because God's providence extends itself to the smallest affairs, his precepts do so, that even in them we may be in the fear of the Lord, as we are under his eye and care. And yet the significancy and tendency of these statutes, which seem little, are such that, notwithstanding their minuteness, being fond among the things of God's law, which he has written to us, they are to be accounted great things.
I. The distinction of sexes by the apparel is to be kept up, for the preservation of our own and our neighbour's chastity, Deu 22:5. Nature itself teaches that a difference be made between them in their hair (Co1 11:14), and by the same rule in their clothes, which therefore ought not to be confounded, either in ordinary wear or occasionally. To befriend a lawful escape or concealment it may be done, but whether for sport or in the acting of plays is justly questionable. 1. Some think it refers to the idolatrous custom of the Gentiles: in the worship of Venus, women appeared in armour, and men in women's clothes; this, as other such superstitious usages, is here said to be an abomination to the Lord. 2. It forbids the confounding of the dispositions and affairs of the sexes: men must not be effeminate, nor do the women's work in the house, nor must women be viragos, pretend to teach, or usurp authority, Ti1 2:11, Ti1 2:12. Probably this confounding of garments had been used to gain opportunity of committing uncleanness, and is therefore forbidden; for those that would be kept from sin must keep themselves from all occasions of it and approaches to it.
II. In taking a bird's-nest, the dam must be let go, Deu 22:6, Deu 22:7. The Jews say, "This is the least of all the commandments of the law of Moses," and yet the same promise is here made to the observance of it that is made to the keeping of the fifth commandment, which is one of the greatest, that it may be well with thee, and that thou mayest prolong thy days; for, as disobedience in a small matter shows a very great contempt of the law, so obedience in a small matter shows a very great regard to it. He that let go a bird out of his hand (which was worth two in the bush) purely because God bade him, in that made it to appear that he esteemed all God's precepts concerning all things to be right, and that he could deny himself rather than sin against God. But doth God take care for birds? Co1 9:9. Yes, certainly; and perhaps to this law our Saviour alludes. Luk 12:6, Are not five sparrows sold for two farthings, and not one of them is forgotten before God? This law, 1. Forbids us to be cruel to the brute-creatures, or to take a pleasure in destroying them. Though God has made us wiser than the fowls of heaven, and given us dominion over them, yet we must not abuse them nor rule them with rigour. Let go the dam to breed again; destroy it not, for a blessing is in it, Isa 65:8. 2. It teaches us compassion to those of our own kind, and to abhor the thought of every thing that looks barbarous, and cruel, and ill-natured, especially towards those of the weaker and tender sex, which always ought to be treated with the utmost respect, in consideration of the sorrows wherein they bring forth children. It is spoken of as an instance of the most inhuman cruelty that the mother was dashed to pieces upon her children (Hos 10:14), and that the women with child were ripped open, Amo 1:13. 3. It further intimates that we must not take advantage against any, from their natural affection and the tenderness of their disposition, to do them an injury. The dam could not have been taken if her concern for her eggs or young (unlike to the ostrich) had not detained her upon the next when otherwise she could easily have secured herself by flight. Now, since it is a thousand pities that she should fare the worse for that which is her praise, the law takes care that she shall be let go. The remembrance of this may perhaps, some time or other, keep us from doing a hard or unkind thing to those whom we have at our mercy.
III. In building a house, care must be taken to make it safe, that none might receive mischief by falling from it, Deu 22:8. The roofs of their houses were flat for people to walk on, as appears by many scriptures; now lest any, through carelessness, should fall off them, they must compass them with battlements, which (the Jews say) must be three feet and a half high; if this were not done, and mischief followed, the owner, by his neglect, brought the guilt of blood upon his house. See here, 1. How precious men's lives are to God, who protects them, not only by his providence, but by his law. 2. How precious, therefore, they ought to be to us, and what care we should take to prevent hurt from coming to any person. The Jews say that by the equity of this law they were obliged (and so are we too) to fence, or remove, every thing by which life may be endangered, as to cover draw-wells, keep bridges in repair, and the like, lest, if any perish through our omission, their blood be required at our hand.
IV. Odd mixtures are here forbidden, Deu 22:9, Deu 22:10. Much of this we met with before, Lev 19:19. There appears not any thing at all of moral evil in these things, and therefore we now make no conscience of sowing wheat and rye together, ploughing with horses and oxen together, and of wearing linsey-woolsey garments; but hereby is forbidden either, 1. A conformity to some idolatrous customs of the heathen. Or, 2. That which is contrary to the plainness and purity of an Israelite. They must not gratify their own vanity and curiosity by putting those things together which the Creator in infinite wisdom had made asunder: they must not be unequally yoked with unbelievers, nor mingle themselves with the unclean, as an ox with an ass. Nor must their profession and appearance in the world be motley, or party-coloured, but all of a piece, all of a kind.
V. The law concerning fringes upon their garments, and memorandums of the commandments, which we had before (Num 15:38, Num 15:39), is here repeated, Deu 22:12. By these they were distinguished from other people, so that it might be said, upon the first sight There goes an Israelite, which taught them not to be ashamed of their country, nor the peculiarities of their religion, how much soever their neighbours looked upon them and it with contempt: and they were also put in mind of the precepts upon the particular occasions to which they had reference; and perhaps this law is repeated here because the precepts immediately foregoing seemed so minute that they were in danger of being overlooked and forgotten. The fringes will remind you not to make your garments of linen and woollen, Deu 22:11.

Deuteronomy 22:9-11

9. Thou shalt not sow thy vineyard with divers seeds: lest the fruit of thy seed which thou hast sown, and the fruit of thy vineyard, be defiled.

9. Non seres vineam tuam diversis speciebus seminum, ne forte pollatur fructus seminis quod sevisti, et fruetus vineae.

10. Thou shalt not plow with an ox and an ass together.

10. Non arabis cum bove et asino pariter.

11. Thou shalt not wear a garment of divers sorts, as of woolien and linen together.

11. Non indues te diversa specie, lana et lino pariter.

Thou shalt not sow thy vineyard. These four precepts, which all condemn strange medleys, I doubt not to be supplements of the First Commandment; and the reason, which is subjoined in Deuteronomy, directs us to this, where God declares that the produce of the seed and of the vineyard is polluted, if there be divers mixtures. Whence it appears that nothing else is demanded but that they should cultivate purity. The word indeed, which Moses uses, means to "sanctify," qds kadesh; but, by antiphrasis, it is taken for to "contaminate." To the same effect is what follows, that they should not plough with an ox and an ass together; for this diversity is forbidden on no other account, but because men contract some defilement as soon as they depart from simplicity. Yet, if any one thinks otherwise, I shall not strongly contend with him. It might indeed be objected, that when God forbids animals to be used promiscuously, so that those of different kinds should not be mixed together, He has regard to chastity, [30] and that, by forbidding the fields to be sown with divers seeds, and garments to be woven of divers materials, He would prevent frauds. But the more simple explanation is, that the people were thus retained in purity, lest they should accustom themselves to corrupt habits, and lest they should bring in strange rites from various quarters, or seek, with depraved curiosity, for mixtures which might at length invade the worship of God. For if animals of different species are joined together, the integrity of nature is corrupted, and an adulterine offspring is produced, which degenerates from the institution of God; but, if various kinds of seed should be mixed together, or if a garment should be woven of linen and wool, there would be no danger of deception or fraud in so manifest a matter. It is probable, therefore, that the end which, as I have said, was proposed by God was, that, by cultivating natural and simple habits all their life through, they should keep themselves pure and uncorrupted from every strange vice. On this account Scripture compares strange doctrines to leaven, since by their additions or curtailings they corrupt the pure word of God. (Matthew 16:11.) And this was by no means a useless discipline; when, in trifles, and almost things of nought, the rein was applied to them, so that they should not decline from purity in the very least degree. It was a small matter to interweave a thin thread with a thicker one, and perchance such a process would have been profitable for their general advantage; in some fields, too, a better crop is grown, if the seed is compounded of pure wheat, and some other sort of grain (siligine), as also the union of the horse and ass has been approved of, since thus mules are produced. But God would not allow these things amongst His ancient people, lest, sinking by degrees to greater license, they should at length addict themselves to the practice and customs of the heathen. He therefore uses this preface: "Ye shall keep my statutes," (Leviticus 19:19;) from whence we gather that the people were surrounded with fixed barriers, lest they should defile themselves with foreign vices, and imitate the nations, from which they had been separated. Wherefore this is the sum, that they should abide in God's statutes.

Thou shalt not wear a garment of divers sorts,.... The Jews say nothing is forbidden under the name of sorts but what is spun and wove, as it is said, "thou shalt not wear sheatnez", a thing that is carded, spun, and wove (l); which Ainsworth translates "linsie woolsie", and is explained by what follows: as "of woollen and linen together"; of which See Gill on Leviticus 19:19, whereas Josephus (m) observes, this was granted to the priests only to wear such garments. Bochart (n) affirms it to be false; but that great man is mistaken; the blue, purple, and scarlet, in the priests' garments, were no other than dyed wool; and it is a sentiment in general received by the Jews, that the priests wore no other but woollen and linen in their service; see the note on the above place; otherwise this law is so strictly observed, as not, to sew a woollen garment with linen thread, and so on the contrary (o).

Going deeper and deeper into the manifold relations of the national life, Moses first of all explains in Deu 22:1-12 the attitude of an Israelite, on the one hand, towards a neighbour; and, on the other hand, towards the natural classification and arrangement of things, and shows how love should rule in the midst of all these relations. The different relations brought under consideration are selected rather by way of examples, and therefore follow one another without any link of connection, for the purpose of exhibiting the truth in certain concrete cases, and showing how the covenant people were to hold all the arrangement of God sacred, whether in nature or in social life.
Deu 22:1-3
In Deu 22:1-4 Moses shows, by a still further expansion of Exo 23:4-5, how the property of a neighbour was to be regarded and preserved. If any man saw an ox or a sheep of his brother's (fellow-countryman) going astray, he was not to draw back from it, but to bring it back to his brother; and if the owner lived at a distance, or was unknown, he was to take it into his own house or farm, till he came to seek it. He was also to do the same with an ass or any other property that another had lost.
Deu 22:4
A fallen animal belonging to another he was also to help up (as in Exo 23:5 : except that in this case, instead of a brother generally, an enemy or hater is mentioned).
Deu 22:5
As the property of a neighbour was to be sacred in the estimation of an Israelite, so also the divine distinction of the sexes, which was kept sacred in civil life by the clothing peculiar to each sex, was to be not less but even more sacredly observed. "There shall not be man's things upon a woman, and a man shall not put on a woman's clothes." כּלי does not signify clothing merely, nor arms only, but includes every kind of domestic and other utensils (as in Exo 22:6; Lev 11:32; Lev 13:49). The immediate design of this prohibition was not to prevent licentiousness, or to oppose idolatrous practices (the proofs which Spencer has adduced of the existence of such usages among heathen nations are very far-fetched); but to maintain the sanctity of that distinction of the sexes which was established by the creation of man and woman, and in relation to which Israel was not to sin. Every violation or wiping out of this distinction - such even, for example, as the emancipation of a woman - was unnatural, and therefore an abomination in the sight of God.
Deu 22:6-7
The affectionate relation of parents to their young, which God had established even in the animal world, was also to be kept just as sacred. If any one found a bird's nest by the road upon a tree, or upon the ground, with young ones or eggs, and the mother sitting upon them, he was not to take the mother with the young ones, but to let the mother fly, and only take the young. נקרא for נקרה, as in Exo 5:3. The command is related to the one in Lev 22:28 and Exo 23:19, and is placed upon a par with the commandment relating to parents, by the fact that obedience is urged upon the people by the same promise in both instances (vid., Deu 5:16; Exo 20:12).
Deu 22:8-12
Still less were they to expose human life to danger through carelessness. "If thou build a new house, make a rim (maakeh) - i.e., a balustrade - to thy roof, that thou bring not blood-guiltiness upon thy house, if any one fall from it." The roofs of the Israelitish houses were flat, as they mostly are in the East, so that the inhabitants often lived upon them (Jos 2:6; Sa2 11:2; Mat 10:27). - In Deu 22:9-11, there follow several prohibitions against mixing together the things which are separated in God's creation, consisting partly of a verbal repetition of Lev 19:19 (see the explanation of this passage). - To this there is appended in Deu 22:12 the law concerning the tassels upon the hem of the upper garment (Num 15:37.), which were to remind the Israelites of their calling, to walk before the Lord in faithful fulfilment of the commandments of God (see the commentary upon this passage).
