1 Samuel 20:20

Jonathan caused David to swear again, for the love that he had for him; for he loved him as he loved his own soul.

Then Jonathan said to him, “Tomorrow is the new moon, and you will be missed, because your seat will be empty.

When you have stayed three days, go down quickly and come to the place where you hid yourself when this started, and remain by the stone Ezel.

Behold, I will send the boy, saying, ‘Go, find the arrows!’ If I tell the boy, ‘Behold, the arrows are on this side of you. Take them;’ then come, for there is peace to you and no danger, as the LORD lives.

But if I say this to the boy, ‘Behold, the arrows are beyond you,’ then go your way, for the LORD has sent you away.

Concerning the matter which you and I have spoken of, behold, the LORD is between you and me forever.”
