1 Samuel 19:16-20

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.

And Saul sent messengers to take David: and when they saw the company of the prophets prophesying, and Samuel standing as appointed over them, the Spirit of God was upon the messengers of Saul, and they also prophesied.
