1 Samuel 19:10-11

10Then Saul sought to pin David to the wall with the spear, but he slipped away from Saul’s presence; and he drove the spear into the wall. So David fled and escaped that night.

11Saul also sent messengers to David’s house to watch him and to kill him in the morning. And Michal, David’s wife, told him, saying, “If you do not save your life tonight, tomorrow you will be killed.”
