1 Samuel 20:18-22

18Then Jonathan said to David, ‘Tomorrow we will have the special meal because of the new moon. Nobody will be sitting in your seat, so people will know that you are not there.

19The day after tomorrow, go back to the place where you hid the other time. Wait beside the rock called Ezel.

20I will shoot three arrows towards the rock to see where they go.

21Then I will send a boy to find the arrows. If you are not in danger I will say to the boy, “The arrows are on this side of you. Come and bring them here.” That will mean that you are safe. You can then come out from the place where you are hiding. As surely as the Lord lives, I promise that you will not be in trouble.

22But if I say to the boy, “Look, the arrows are beyond you,” you must run away. It will mean that the Lord has sent you away.
