1 Samuel 20:18-22

18And Jonathan said to him, To-morrow is the new moon; and thou wilt be missed, for thy seat will be empty;

19but on the third day thou shalt go down quickly, and come to the place where thou didst hide thyself on the day of the business, and abide by the stone Ezel.

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

21And behold, I will send the lad, [saying,] Go, find the arrows. If I expressly say to the lad, Behold, the arrows are on this side of thee, take them; then come, for there is peace for thee, and it is nothing; [as] Jehovah liveth.

22But if I say thus to the youth: Behold, the arrows are beyond thee, — go thy way; for Jehovah sends thee away.
