1 Samuel 20:21-22

And, behold, I will send a lad, saying, Go, find out the arrows. If I expressly say unto the lad, Behold, the arrows are on this side of thee, take them; then come thou: for there is peace to thee, and no hurt; as the LORD liveth. But if I say thus unto the young man, Behold, the arrows are beyond thee; go thy way: for the LORD hath sent thee away.
