1 Samuel 19:9-12
9 But an evil spirit from the Lord came upon Saul as he was sitting in his house with his spear in his hand. While David was playing the harp,
10 Saul tried to pin him to the wall with his spear, but David eluded him as Saul drove the spear into the wall. That night David made good his escape.
11 Saul sent men to David’s house to watch it and to kill him in the morning. But Michal, David’s wife, warned him, “If you don’t run for your life tonight, tomorrow you’ll be killed.”
12 So Michal let David down through a window, and he fled and escaped.
