1 Samuel 20:18-22

18Then Jonathan said to David, “Tomorrow is the New Moon; and you will be missed, because your seat will be empty.

19And when you have stayed three days, go down quickly and come to the place where you hid on the day of the deed; and remain by the stone Ezel.

20Then I will shoot three arrows to the side, as though I shot at a target;

21and there I will send a lad, saying, ‘Go, find the arrows.’ If I expressly say to the lad, ‘Look, the arrows are on this side of you; get them and come’—then, as the Lord lives, there is safety for you and no harm.

22But if I say thus to the young man, ‘Look, the arrows are beyond you’—go your way, for the Lord has sent you away.
