1 Samuel 19:18-20

18Now David fled and escaped, and he came to Samuel at Ramah and told him all that Saul had done to him. And he and Samuel went and lived at Naioth.

19And it was told Saul, "Behold, David is at Naioth in Ramah."

20Then Saul sent messengers to take David, and when they saw the company of the prophets prophesying, and Samuel standing as head over them, the Spirit of God came upon the messengers of Saul, and they also prophesied.
