1 Samuel 20:18-23

18Then Jonathan said to him, "Tomorrow is the new moon, and you will be missed, because your seat will be empty.

19On the third day go down quickly to the place where you hid yourself when the matter was in hand, and remain beside the stone heap.

20And I will shoot three arrows to the side of it, as though I shot at a mark.

21And behold, I will send the boy, saying, 'Go, find the arrows.' If I say to the boy, 'Look, the arrows are on this side of you, take them,' then you are to come, for, as the Lord lives, it is safe for you and there is no danger.

22But if I say to the youth, 'Look, the arrows are beyond you,' then go, for the Lord has sent you away.

23And as for the matter of which you and I have spoken, behold, the Lord is between you and me forever."
