1 Samuel 20:38
And Jonathan cried after the lad, Make speed, haste, stay not. And Jonathan’s lad gathered up the arrows, and came to his master. And Jonathan cried after the lad, Make speed, haste, stay not. And Jonathan’s lad gathered up the arrows, and came to his master.
This cry belongs to the history that followed David's killing of Goliath, when Saul kept David with him and would not let him go back to his father's house. In that history the soul and heart of Jonathan was knit with David's, and Jonathan loved him as his own soul. That sacred bond of union was the Lord's doing, and it remained unbroken till the death of Saul and Jonathan.
Jonathan and David made a covenant to be united as brethren. As a sign of that bond Jonathan gave David his robe and his garments, with his sword and his bow and his girdle. God's providence had connected David with Saul so that by wise behavior David might obtain the confidence of the people, and by a long course of hardships be led to put entire trust in God while God was preparing him to become ruler of His people. In keeping with that preparation David was trusted with important responsibilities while keeping modesty and winning the affection of the people and the royal household.
The cry itself shows Jonathan carrying out the agreed plan in the field where David hid, to make known Saul's intention toward him. By it Jonathan warned David that Saul was enraged at David's absence from the new-moon feast and was determined to put him to death, so David must flee for his life. The warning confirmed David's innocence and Jonathan's discovery that Saul's dark passion would not spare David, and in this Jonathan served as the means of preserving David's life when Saul would try to kill him. It led to their sorrowful parting when they fell on each other's neck and wept bitterly, with Jonathan sending David away in peace under their sworn covenant that the Lord be between them and between their seed forever.
