1 Samuel 20:21-22

21and there I will send a lad, saying, ‘Go, find the arrows.’ If I expressly say to the lad, ‘Look, the arrows are on this side of you; get them and come’—then, as the Lord lives, there is safety for you and no harm.

22But if I say thus to the young man, ‘Look, the arrows are beyond you’—go your way, for the Lord has sent you away.
