(17) And Jonathan caused David to swear again.--Throughout this touching interview it is the prince who appears as the suppliant for the outlaw's ruture kind offices. Jonathan--looking forward with absolute certainty to the day when his persecuted friend would be on the throne, and he in his grave--dreaded for his own fatherless children the fate which too probably awaited them, it having been in all ages a common custom in the East, when the dynasty was violently changed, to put to death the children and near relations of the former king.

Verse 17. - Jonathan caused David to swear again. So strong was his conviction in David's future kingdom, and his wish that there should be an unbroken bond of love between the two families, that he makes David solemnly repeat his promise. The Septuagint and Vulgate, by altering the vowels, read, "And Jonathan sware again to David." At first sight this interpretation seems most in accordance with the reason given for the renewal of the oath, namely, Jonathan's own love; but the Masoretic text agrees better with what has gone before, and with his wish that their covenant under no change of circumstances should be broken.

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!And Jonathan caused David to swear again,.... Or Jonathan added to make David swears (u); having sworn himself to make a covenant of friendship with David and his family, he moved and insisted on it, that David should swear to keep covenant with him, and his family:

because he loved him; it was not so much for the good and safety of his offspring that he made this motion, and was so desirous of renewing and enlarging his covenant with David, as it was his strong love and affection for him; being on that account desirous that there might be the strictest friendship imaginable retained between the two families; or he made him swear by his love to him, as some understand it, which is not so likely; the former sense is better, for he himself sware by the Lord, 1 Samuel 20:12,

for he loved him as his own soul; or "with the love of his soul" (w); with the most cordial affection, with a truly hearty and sincere love, see 1 Samuel 18:1.
