1 Samuel 20:18-22

18Then Jonathan said to him, “Tomorrow is the New Moon. You’ll be missed because your seat will be empty.

19On the third day, you must go down quickly and come to the place where you hid as you did on that day, and remain close to the stone Ezel.

20I will shoot three arrows to the side of it, as though I were shooting at a target.

21Now look, I will send a lad saying, ‘Go, find the arrows.’ If I specifically say to the lad, ‘See, the arrows are on this side of you—get them,’ then come; for it is safe for you and no danger, as Adonai lives.

22But if I say to the boy: ‘Look, the arrows are beyond you,’ then go your way, for Adonai has released you.
