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!
But if I say thus unto the young man, behold, the arrows are beyond thee,.... Being shot to a greater distance than where the young man was:
go thy way, for the Lord hath sent thee away; then he was to depart directly, without staying to have any conversation with Jonathan, which would not be safe for either of them, and so make the best of his way into the country, and escape for his life; for so it was ordered by the providence of God, that he must not stay, but be gone immediately: the signals were these, that if things were favourable, then he would shoot his arrows on one side of the lad, and David might come out and show himself at once; but if not, he would shoot them beyond him, by which he might know that he must flee for his life.
