1 Samuel 20:14-17

LXX2012(i) 14 And if indeed I continue to live, then shall you deal mercifully with me; and if I indeed die, 15 you shall not withdraw your mercy from my house for ever: and if you do not, when the Lord cuts off the enemies of David each from the face of the earth, 16 [should it happen] that the name of Jonathan be discovered by the house of David, then let the Lord seek out the enemies of David. 17 And Jonathan swore yet again to David, because he loved the soul of him that loved him.
