1 Samuel 19:15-19

And Saul sent the messengers again to see David, saying, Bring him up to me in the bed, that I may slay him.

And when the messengers were come in, behold, there was an image in the bed, with a pillow of goats’ hair for his bolster.

And Saul said unto Michal, Why hast thou deceived me so, and sent away mine enemy, that he is escaped? And Michal answered Saul, He said unto me, Let me go; why should I kill thee?

So David fled, and escaped, and came to Samuel to Ramah, and told him all that Saul had done to him. And he and Samuel went and dwelt in Naioth.

And it was told Saul, saying, Behold, David is at Naioth in Ramah.
