Then Saul sent troops to watch David’s house. They were told to kill David when he came out the next morning. But Michal, David’s wife, warned him, “If you don’t escape tonight, you will be dead by morning.”
So she helped him climb out through a window, and he fled and escaped.
Then she took an idol and put it in his bed, covered it with blankets, and put a cushion of goat’s hair at its head.

“Why have you betrayed me like this and let my enemy escape?” Saul demanded of Michal. “I had to,” Michal replied. “He threatened to kill me if I didn’t help him.”
