1 Samuel 24:18

May the LORD therefore be judge, and give sentence between me and you, and see, and plead my cause, and deliver me out of your hand.”

It came to pass, when David had finished speaking these words to Saul, that Saul said, “Is that your voice, my son David?” Saul lifted up his voice and wept.

He said to David, “You are more righteous than I; for you have done good to me, whereas I have done evil to you.

For if a man finds his enemy, will he let him go away unharmed? Therefore may the LORD reward you good for that which you have done to me today.

Now, behold, I know that you will surely be king, and that the kingdom of Israel will be established in your hand.

Swear now therefore to me by the LORD that you will not cut off my offspring after me, and that you will not destroy my name out of my father’s house.”
