1 Samuel (Author Compiled by Isaiah from records of Samuel, David, Nathan, and Gad.)
18:17And Saul said to David, Behold my elder daughter Merab, her will I give thee to wife: only be thou valiant for me, and fight the LORD'S battles. For Saul said, Let not mine hand be upon him, but let the hand of the Philistines be upon him.
