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.

19The following day hurry down and go to the place where you hid on the day this incident began and stay beside the rock Ezel.

20I will shoot three arrows beside it as if I’m aiming at a target.

21Then I will send a servant and say, ‘Go and find the arrows! ’ Now, if I expressly say to the servant, ‘Look, the arrows are on this side of you — get them,’ then come, because as the Lord lives, it is safe for you and there is no problem.

22But if I say this to the youth, ‘Look, the arrows are beyond you! ’ then go, for the Lord is sending you away.
