1 Samuel 20
20 And on the third day I will send arrows from my bow against its side as if at a mark.
21 Ref And I will send my boy to have a look for the arrow. And if I say to him, See, the arrow is on this side of you; take it up! then you may come; for there is peace for you and no evil, by the living Lord.
22 Ref But if I say to the boy, See, the arrow has gone past you: then go on your way, for the Lord has sent you away.
