1 Samuel 20:3

20:3 Taking an oath, David again said, “Your father is very much aware of the fact that I have found favor with you, and he has thought, ‘Don’t let Jonathan know about this, or he will be upset.’ But as surely as the Lord lives and you live, there is about one step between me and death!”

1 Samuel 20:21

20:21 When I send a boy after them, I will say, “Go and find the arrows.” If I say to the boy, ‘Look, the arrows are on this side of you; get them,’ then come back. For as surely as the Lord lives, you will be safe and there will no problem.
