1 Samuel 20:15-24 New King James Version (NKJV)
15 but you shall not [a]cut off your kindness from my [b]house forever, no, not when the Lord has cut off every one of the enemies of David from the face of the earth.” 16 So Jonathan made a covenant with the [c]house of David, saying, “Let the Lord require it at the hand of David’s enemies.”
17 Now Jonathan again caused David to vow, because he loved him; for he loved him as he loved his own soul. 18 Then Jonathan said to David, “Tomorrow is the New Moon; and you will be missed, because your seat will be empty. 19 And when you have stayed three days, go down quickly and come to the place where you hid on the day of the deed; and remain by the stone Ezel. 20 Then I will shoot three arrows to the side, as though I shot at a target; 21 and there I will send a lad, saying, ‘Go, find the arrows.’ If I expressly say to the lad, ‘Look, the arrows are on this side of you; get them and come’—then, as the Lord lives, there is safety for you and no harm. 22 But if I say thus to the young man, ‘Look, the arrows are beyond you’—go your way, for the Lord has sent you away. 23 And as for the matter which you and I have spoken of, indeed the Lord be between you and me forever.”
24 Then David hid in the field. And when the New Moon had come, the king sat down to eat the feast.
