1 Samuel 20:12-27

And Jonathan said unto David, O LORD God of Israel, when I have sounded my father about to morrow any time, or the third day, and, behold, if there be good toward David, and I then send not unto thee, and shew it thee; the LORD do so and much more to Jonathan: but if it please my father to do thee evil, then I will shew it thee, and send thee away, that thou mayest go in peace: and the LORD be with thee, as he hath been with my father. And thou shalt not only while yet I live shew me the kindness of the LORD, that I die not: but also thou shalt not cut off thy kindness from my house for ever: no, not when the LORD 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, Let the LORD even require it at the hand of David's enemies. And Jonathan caused David to swear again, because he loved him: for he loved him as he loved his own soul. Then Jonathan said to David, To morrow is the new moon: and thou shalt be missed, because thy seat will be empty. And when thou hast stayed three days, then 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 a lad, saying, Go, find out the arrows. If I expressly say unto the lad, Behold, the arrows are on this side of thee, take them; then come thou: for there is peace to thee, and no hurt; as the LORD liveth. But if I say thus unto the young man, Behold, the arrows are beyond thee; go thy way: for the LORD hath sent thee away. And as touching the matter which thou and I have spoken of, behold, the LORD be between thee and me for ever. So David hid himself in the field: and when the new moon was come, the king sat him down to eat meat. And the king sat upon his seat, as at other times, even upon a seat by the wall: and Jonathan arose, and Abner sat by Saul's side, and David's place was empty. Nevertheless Saul spake not any thing that day: for he thought, Something hath befallen him, he is not clean; surely he is not clean. And it came to pass on the morrow, which was the second day of the month, that David's place was empty: and Saul said unto Jonathan his son, Wherefore cometh not the son of Jesse to meat, neither yesterday, nor to day?
