Jonathan said - O Lord God of Israel - There is, most evidently, something wanting in this verse. The Septuagint has, The Lord God of Israel doth Know. The Syriac and Arabic, The Lord God of Israel is Witness. Either of these makes a good sense. But two of Dr. Kennicott's MSS. supply the word חי chai, "liveth;" and the text reads thus, As the Lord God of Israel Liveth, when I have sounded my father - if there be good, and I then send not unto thee, and show it thee, the Lord do so and much more to Jonathan. This makes a still better sense.

And Jonathan said unto David, O Lord God of Israel,.... Or by the Lord God of Israel, I swear unto thee; for this is the form of the oath, as Jarchi and Kimchi observe:

when I have sounded my father about tomorrow any time, or the third day; searched, inquired, and found out how his disposition is:

and, behold, if there be good toward David; if he is well disposed to him, as may appear by speaking respectfully of him, or kindly inquiring after him, and by being satisfied with the account given him:

and I then send not unto thee, and show it thee; then let the vengeance of God fall upon me in some remarkable manner or another, as follows; or "shall I not then send unto thee, and show it thee" (t)? certainly I will; that is, I will send a messenger to thee to acquaint thee with it, who shall tell it, and cause thee to hear it, as from myself.

(t) "an non tune mitterem?" Junius & Tremellius; "nonne tunc mittam ad te?" so some in Vatablus.

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 (1 Samuel 20:12, 1 Samuel 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 (1 Samuel 20:14-16); and lastly, he made David swear again concerning his love (1 Samuel 20:17), and then gave him the sign by which he would communicate the promised information (1 Samuel 20:18-23).

1 Samuel 20:12-15

1 Samuel 20:12 and 1 Samuel 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 1 Samuel 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 1 Samuel 20:14 and 1 Samuel 20:15 the Masoretic text gives no appropriate meaning. Luther's rendering, in which he follows the Rabbins and takes the first ולא (1 Samuel 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 1 Samuel 20:14 into ולוּ or ולא, according to the analogy of the form לוּא (1 Samuel 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.

And Jonathan said unto David, O LORD God of Israel, when I have sounded my father about to morrow any time, or the third day, and, behold, if there be good toward David, and I then send not unto thee, and show it thee;

20:12 O Lord God - Do thou hear and judge between us. It is an abrupt speech which is usual in great passions.

sounded: Heb. searched

shew...: Heb. uncover thine ear

20:11-23 Jonathan faithfully promises that he would let David know how he found his father affected towards him. It will be kindness to ourselves and to ours, to secure an interest in those whom God favours, and to make his friends ours. True friendship rests on a firm basis, and is able to silence ambition, self-love, and undue regard for others. But who can fully understand the love of Jesus, who gave himself as a sacrifice for rebellious, polluted sinners! how great then ought to be the force and effects of our love to him, to his cause, and his people!
