1 Samuel 18:14-18

David was successful in all his ways, for the Lord was with him.

But all Israel and Judah loved David, for he would go out to battle and return before them.

But David said to Saul, “Who am I, and who is my family, or my father’s family in Israel, that I should be the king’s son-in-law?”
