1 Samuel 20:18

Jonathan's plan would allow David to get the message even if there could be no face-to-face meeting. The boy's presence reduced suspicion and gave Jonathan an excuse to go to the field. As it happened, only the boy went with Jonathan to the field. When the boy left, David could talk to Jonathan directly (1 Samuel 20:40–42).

THEIR COVENANT RENEWED BY OATH. (Sa1 20:11-23)

Jonathan said to David, Come, let us go into the field--The private dialogue, which is here detailed at full length, presents a most beautiful exhibition of these two amiable and noble-minded friends. Jonathan was led, in the circumstances, to be the chief speaker. The strength of his attachment, his pure disinterestedness, his warm piety, his invocation to God (consisting of a prayer and a solemn oath combined), the calm and full expression he gave of his conviction that his own family were, by the divine will, to be disinherited, and David elevated to the possession of the throne, the covenant entered into with David on behalf of his descendants, and the imprecation (Sa1 20:16) denounced on any of them who should violate his part of the conditions, the reiteration of this covenant on both sides (Sa1 20:17) to make it indissoluble--all this indicates such a power of mutual affection, such magnetic attractiveness in the character of David, such susceptibility and elevation of feeling in the heart of Jonathan, that this interview for dramatic interest and moral beauty stands unrivalled in the records of human friendship.

Here, I. Jonathan protests his fidelity to David in his distress. Notwithstanding the strong confidence David had in Jonathan, yet, because he might have some reason to fear that his father's influence, and his own interest, should make him warp, or grow cool towards him, Jonathan thought it requisite solemnly to renew the professions of his friendship to him (Sa1 20:9): "Far be it from thee to think that I suspect thee of any crime for which I should either slay thee myself or deliver thee to my father; no, if thou hast any jealousy of that, Come let us go into the field (Sa1 20:11), and talk it over more fully." He did not challenge him to the field to fight him for an affront, but to fix him in his friendship. He faithfully promised him that he would let him know how, upon trial, he found his father affected towards him, and would make the matter neither better nor worse than it was. "If there be good towards thee, I will show it thee, that thou mayest be easy (Sa1 20:12), if evil, I will send thee away, that thou mayest be safe" (Sa1 20:13); and thus he would help to deliver him from the evil if it were real and from the fear of evil if it were but imaginary. For the confirmation of his promise he appeals to God, 1. As a witness (Sa1 20:12): "O Lord God of Israel, thou knowest I mean sincerely, and think as I speak." The strength of his passion made the manner of his speaking concise and abrupt. 2. As a judge: "The Lord do so and much more to Jonathan (Sa1 20:13), if I speak deceitfully, or break my word with my friend." He expressed himself thus solemnly that David might be abundantly assured of his sincerity. And thus God has confirmed his promises to us, that we might have strong consolation, Heb 6:17, Heb 6:18. Jonathan adds to his protestations his hearty prayers: "The Lord be with thee, to protect and prosper thee, as he has been formerly with my father, though now he has withdrawn." Thus he imitates his belief that David would be in his father's place, and his good wishes that he might prosper in it better than his father now did.
II. He provides for the entail of the covenant of friendship with David upon his posterity, Sa1 20:14-16. He engages David to be a friend to his family when he was gone (Sa1 20:15): Thou shalt promise that thou wilt not cut off thy kindness from my house for ever. This he spoke from a natural affection he had to his children, whom he desired it might go well with after his decease, and for whose future welfare he desired to improve his present interest. It also intimates his firm belief of David's advancement, and that it would be in the power of his hand to do a kindness or unkindness to his seed; for, in process of time, the Lord would cut off his enemies, Saul himself was not expected; then "Do not thou cut off thy kindness from my house, nor revenge my father's wrongs upon my children." The house of David must likewise be bound to the house of Jonathan from generation to generation; he made a covenant (Sa1 20:16) with the house of David. Note, True friends cannot but covet to transmit to theirs after them their mutual affections. Thy own friend, and thy father's friend, forsake not. This kindness, 1. He calls the kindness of the Lord, because it is such kindness as God shows to those he takes into covenant with himself; for he is a God to them and to their seed; they are beloved for the fathers' sakes. 2. He secures it by an imprecation (Sa1 20:16): The Lord require it at the hand of David's seed (for of David himself he had no suspicion) if they prove so far David's enemies as to deal wrongfully with the posterity of Jonathan, David's friend. He feared lest David, or some of his, should hereafter be tempted, for the clearing and confirming of their title to the throne, to do by his seed as Abimelech had done by the sons of Gideon (Jdg 9:5), and this he would effectually prevent; but the reason given (Sa1 20:17) why Jonathan was so earnest to have the friendship entailed is purely generous, and has nothing of self in it; it was because he loved him as he loved his own soul, and therefore desired that he and his might be beloved by him. David, though now in disgrace at court and in distress, was as amiable in the eyes of Jonathan as ever he had been, and he loved him never the less for his father's hating him, so pure were the principles on which his friendship was built. Having himself sworn to David, he caused David to swear to him, and (as we read it) to swear again, which David consented to (for he that bears an honest mind does not startle at assurances), to swear by his love to him, which he looked upon as a sacred thing. Jonathan's heart was so much upon it that, when they parted this time, he concluded with a solemn appeal to God: The Lord be between me and thee for ever (Sa1 20:23), that is, "God himself be judge between us and our families for ever, if on either side this league of friendship be violated." It was in remembrance of this covenant that David was kind to Mephibosheth, Sa2 9:7; Sa2 21:7. It will be a kindness to ourselves and ours to secure an interest in those whom God favours and to make his friends ours.
III. He settles the method of intelligence, and by what signs and tokens he would give him notice how his father stood affected towards him. David would be missed the first day, or at least the second day, of the new moon, and would be enquired after, Sa1 20:18. On the third day, by which time he would have returned from Bethlehem, he must be at such a place (Sa1 20:19), and Jonathan would come towards that place with his bow and arrows to shoot for diversion (Sa1 20:20), would send his lad to fetch his arrows, and, if they were shot short of the lad, David must take it for a signal of safety, and not be afraid to show his head (Sa1 20:21); but, if he shot beyond the lad, it was a signal of danger, and he must shift for his safety, Sa1 20:22. This expedient he fixed lest he should not have the opportunity, which yet it proved he had, of talking with David, and making the report by word of mouth.

Show me the kindness of the Lord - When thou comest to the kingdom, if I am alive, thou shalt show kindness to me, and thou shalt continue that kindness to my family after me.

Then Jonathan said to David, tomorrow is the new moon,.... The first day of the month, as David had before observed, 1 Samuel 20:5,

and thou shalt be missed, because thy seat will be empty; or be inquired after, because not in his usual place at mealtime.

Thy seat, i.e. the place where David used to sit at meals with Saul. See .

In the field, where they were both entirely free from observation, Jonathan first of all renewed his covenant with David, by vowing to him on oath that he would give him information of his father's feelings towards him (Sa1 20:12, Sa1 20:13); and then entreated him, with a certain presentiment that David would one day be king, even then to maintain his love towards him and his family for ever (Sa1 20:14-16); and lastly, he made David swear again concerning his love (Sa1 20:17), and then gave him the sign by which he would communicate the promised information (Sa1 20:18-23).
Sa1 20:12-15
Sa1 20:12 and Sa1 20:13 are connected. Jonathan commences with a solemn invocation of God: "Jehovah, God of Israel!" and thus introduces his oath. We have neither to supply "Jehovah is witness," nor "as truly as Jehovah liveth," as some have suggested. "When I inquire of my father about this time to-morrow, the day after to-morrow (a concise mode of saying 'to-morrow or the day after'), and behold it is (stands) well for David, and then I do not send to thee and make it known to thee, Jehovah shall do so to Jonathan," etc. ("The Lord do so," etc., the ordinary formula used in an oath: see Sa1 14:44). The other case is then added without an adversative particle: "If it should please my father evil against thee (lit. as regards evil), "I will make it known to thee, and let thee go, that thou mayest go in peace; and Jehovah be with thee, as He has been with my father." In this wish there is expressed the presentiment that David would one day occupy that place in Israel which Saul occupied then, i.e., the throne. - In Sa1 20:14 and Sa1 20:15 the Masoretic text gives no appropriate meaning. Luther's rendering, in which he follows the Rabbins and takes the first ולא (Sa1 20:14) by itself, and then completes the sentence from the context ("but if I do it not, show me no mercy, because I live, not even if I die"), contains indeed a certain permissible sense when considered in itself; but it is hardly reconcilable with what follows, "and do not tear away thy compassion for ever from my house." The request that he would show no compassion to him (Jonathan) even if he died, and yet would not withdraw his compassion from his house for ever, contains an antithesis which would have been expressed most clearly and unambiguously in the words themselves, if this had been really what Jonathan intended to say. De Wette's rendering gives a still more striking contradiction: "But let not (Jehovah be with thee) if I still live, and thou showest not the love of Jehovah to me, that I do not, and thou withdrawest not thy love from my house for ever." There is really no other course open than to follow the Syriac and Arabic, as Maurer, Thenius, and Ewald have done, and change the ולא in the first two clauses in Sa1 20:14 into ולוּ or ולא, according to the analogy of the form לוּא (Sa1 14:30), and to render the passage thus: "And mayest thou, if I still live, mayest thou show to me the favour of the Lord, and not if I do, not withdraw thy favour from my house for ever, not even (ולא) when Jehovah shall cut off the enemies of David, every one from the face of the earth!" "The favour of Jehovah" is favour such as Jehovah shall cut off," etc., shows very clearly Jonathan's conviction that Jehovah would give to David a victory over all his enemies.
Sa1 20:16
Thus Jonathan concluded a covenant with the house of David, namely, by bringing David to promise kindness to his family for ever. The word בּרית must be supplied in thought to יכרת, as in Sa1 22:8 and Ch2 7:18. "And Jehovah required it (what Jonathan had predicted) at the hand of David's enemies." Understood in this manner, the second clause contains a remark of the historian himself, namely, that Jonathan's words were really fulfilled in due time. The traditional rendering of וּבקּשׁ as a relative preterite, with אמר understood, "and said, Let Jehovah take vengeance," is not only precluded by the harshness of the introduction of the word "saying," but still more by the fact, that if אמר (saying) is introduced between the copula vav and the verb בּקּשׁ, the perfect cannot stand for the optative בּקּשׁ, as in Jos 22:23.
Sa1 20:17
"And Jonathan adjured David again by his love to him, because he loved him as his own soul" (cf. Sa1 18:1, Sa1 18:3); i.e., he once more implored David most earnestly with an oath to show favour to him and his house.
Sa1 20:18-19
He then discussed the sign with him for letting him know about his father's state of mind: "To-morrow is new moon, and thou wilt be missed, for thy seat will be empty," sc., at Saul's table (see at Sa1 20:5). "And on the third day come down quickly (from thy sojourning place), and go to the spot where thou didst hide thyself on the day of the deed, and place thyself by the side of the stone Ezel." The first words in this (19th) verse are not without difficulty. The meaning "on the third day" for the verb שׁלּשׁ cannot be sustained by parallel passages, but is fully established, partly by השּׁלשׁית, the third day, and partly by the Arabic usage (vid., Ges. Thes. s. v.). מאד after תּרד, lit., "go violently down," is more striking still. Nevertheless the correctness of the text is not to be called in question, since שׁלּשׁתּ is sustained by τρισσεύσει in the Septuagint, and מאד תּרד by descende ergo festinus in the Vulgate, and also by the rendering in the Chaldee, Arabic, and Syriac versions, "and on the third day thou wilt be missed still more," which is evidently merely a conjecture founded upon the context. The meaning of המּעשׂה בּיום is doubtful. Gesenius, De Wette, and Maurer render it "on the day of the deed," and understand it as referring to Saul's deed mentioned in Sa1 19:2, viz., his design of killing David; others render it "on the day of business," i.e., the working day (Luther, after the lxx and Vulgate), but this is not so good a rendering. The best is probably that of Thenius, "on the day of the business" (which is known to thee). Nothing further can be said concerning the stone Ezel than that Ezel is a proper name.
Sa1 20:20
"And I will shoot off three arrows to the side of it (the stone Ezek), to shoot for me at the mark," i.e., as if shooting at the mark. The article attached to החצּים is either to be explained as denoting that the historian assumed the thing as already well known, or on the supposition that Jonathan went to the field armed, and when giving the sign pointed to the arrows in his quiver. In the word צדּה the Raphe indicates that the suffix of ־ה is not a mere toneless ה, although it has no mappik, having given up its strong breathing on account of the harsh צ sound.
Sa1 20:21
"And, behold (הנּה, directing attention to what follows as the main point), I will send the boy (saying), Go, get the arrows. If I shall say to the boy, Behold, the arrows are from thee hitherwards, fetch them; then come, for peace is to thee, and it is nothing, as truly as Jehovah liveth."
Sa1 20:22
"But if I say to the youth, Behold, the arrows are from thee farther off; then go, for Jehovah sendeth thee away," i.e., bids thee flee. The appointment of this sign was just as simple as it was suitable to the purpose.
Sa1 20:23
This arrangement was to remain an eternal secret between them. "And (as for) the word that we have spoken, I and thou, behold, the Lord is between me and thee for ever," namely, a witness and judge in case one of us two should break the covenant (vid., Gen 31:48-49). This is implied in the words, without there being any necessity to assume that עד had dropped out of the text. "The word" refers not merely to the sign agreed upon, but to the whole matter, including the renewal of the bond of friendship.
