1 Samuel 20:18-23

18Then Jonathan said unto him, Tomorrow is the new moon: and thou shalt be missed, because thy seat will be empty.

19And when thou hast stayed three days, thou shalt go down quickly, and come to the place where thou didst hide thyself when the business was in hand, and shalt remain by the stone Ezel.

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

21And, behold, I will send the lad, saying, Go, find the arrows. If I say unto the lad, Behold, the arrows are on this side of thee: take them, and come; for there is peace to thee and no hurt, as the LORD liveth.

22But if I say thus unto the boy, Behold, the arrows are beyond thee: go thy way; for the LORD hath sent thee away.

23And as touching the matter which thou and I have spoken of, behold, the LORD is between thee and me for ever.
