1 Samuel 18:12-18
English Standard Version
Chapter 18
12Saul was afraid of David because the Lord was with him but had departed from Saul. 13So Saul removed him from his presence and made him a commander of a thousand. And he went out and came in before the people. 14And David had success in all his undertakings, for the Lord was with him. 15And when Saul saw that he had great success, he stood in fearful awe of him. 16But all Israel and Judah loved David, for he went out and came in before them.
17Then Saul said to David, "Here is my elder daughter Merab. I will give her to you for a wife. Only be valiant for me and fight the Lord 's battles." For Saul thought, "Let not my hand be against him, but let the hand of the Philistines be against him."
18And David said to Saul, "Who am I, and who are my relatives, my father 's clan in Israel, that I should be son-in-law to the king?"
