1 Samuel 19:8-12

When there was war again, David went out and fought the Philistines and defeated them with great slaughter, so that they fled from him.

Now there was an evil spirit from the Lord on Saul as he was sitting in his house with his spear in his hand, and David was playing the harp with his hand.

And Saul tried to pin David to the wall with the spear, but he escaped from Saul’s presence, so that he stuck the spear into the wall. And David fled and escaped that night.

Then Saul sent messengers to David’s house to watch him, in order to put him to death in the morning. But Michal, David’s wife, informed him, saying, “If you do not save your life tonight, tomorrow you will be put to death!”

So Michal let David down through a window, and he went and fled, and escaped.
