1 Samuel 20:14-17

KJV(i) 14 And thou shalt not only while yet I live show me the kindness of the LORD, that I die not: 15 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. 16 So Jonathan made a covenant with the house of David, saying, Let the LORD even require it at the hand of David's enemies. 17 And Jonathan caused David to swear again, because he loved him: for he loved him as he loved his own soul.
