1 Samuel 20:9-22

And Jonathan said, Far be it from thee; for if I should at all know that evil were determined by my father to come upon thee, then would not I tell it thee? Then said David to Jonathan, Who shall tell me if perchance thy father answer thee roughly? And Jonathan said unto David, Come, and let us go out into the field. And they went out both of them into the field. And Jonathan said unto David, Jehovah, the God of Israel, be witness: when I have sounded my father about this time to-morrow, or the third day, behold, if there be good toward David, shall I not then send unto thee, and disclose it unto thee? Jehovah do so to Jonathan, and more also, should it please my father to do thee evil, if I disclose it not unto thee, and send thee away, that thou mayest go in peace: and Jehovah be with thee, as he hath been with my father. And thou shalt not only while yet I live show me the lovingkindness of Jehovah, that I die not; but also thou shalt not cut off thy kindness from my house for ever; no, not when Jehovah hath cut off the enemies of David every one from the face of the earth. So Jonathan made a covenant with the house of David, saying, And Jehovah will require it at the hand of David’s enemies. And Jonathan caused David to swear again, for the love that he had to him; for he loved him as he loved his own soul. Then Jonathan said unto him, To-morrow is the new moon: and thou wilt be missed, because thy seat will be empty. And when thou hast stayed three days, thou shalt go down quickly, and come to the place where thou didst hide thyself when the business was in hand, and shalt remain by the stone Ezel. And I will shoot three arrows on the side thereof, as though I shot at a mark. And, behold, I will send the lad, saying, Go, find the arrows. If I say unto the lad, Behold, the arrows are on this side of thee; take them, and come; for there is peace to thee and no hurt, as Jehovah liveth. But if I say thus unto the boy, Behold, the arrows are beyond thee; go thy way; for Jehovah hath sent thee away.
