1 Samuel 18:27–29
27 David arose and went, along with his men, and killed two hundred of the Philistines. And David brought their foreskins, which were given in full number to the king, that he might become the king's son-in-law. And Saul gave him his daughter Michal for a wife. 28 But when Saul saw and knew that the LORD was with David, and that Michal, Saul's daughter, loved him, 29 Saul was even more afraid of David. So Saul was David's enemy continually.
1 Samuel 19:23–24
23 And he went there to Naioth in Ramah. And the Spirit of God came upon him also, and as he went he prophesied until he came to Naioth in Ramah. 24 And he too stripped off his clothes, and he too prophesied before Samuel and lay naked all that day and all that night. Thus it is said, “Is Saul also among the prophets?”
