1 Samuel 18:10-19 - Saul Attempts To Kill David
10 The next day, while David was playing the lyre as he had before, the evil spirit from the LORD attacked Saul, and he began to rave inside the house with a spear in his hand. 11 Saul hurled it, thinking, "I'll pin David to the wall." But David escaped from him twice.
12 Now Saul was afraid of David because the LORD was with him and had departed from Saul. 13 Saul removed David from his presence and made him an officer over a division of soldiers. So David led the troops in battle. 14 David was successful in all that he did, for the LORD was with him. 15 When Saul saw that David was highly successful, he feared him. 16 But all Israel and Judah loved David because he led them in battle. 17 Saul told David, "Here is my older daughter Merab. I'll give her to you as a wife. Just be an excellent soldier for me and fight the LORD's battles." Now Saul told himself, "I won't harm him myself. Instead, I'll let the Philistines harm him."
18 David told Saul, "Who am I and what is my life or my father's family in Israel that I should be the king's son-in-law?" 19 And when the time came to give Saul's daughter Merab to David, she was given as a wife to Adriel of Meholah.
