1 Samuel 19:18-24

So David fled and escaped and came to Samuel at Ramah, and told him everything that Saul had done to him. And he and Samuel went and stayed in Naioth. Saul was told, “David is at Naioth in Ramah.” Then Saul sent messengers to take David; but when they saw the group of prophets prophesying, and Samuel standing and presiding over them, the Spirit of God came on the messengers of Saul; and they also prophesied. When Saul was informed, he sent other messengers, and they also prophesied. So Saul sent messengers again, the third time, and they prophesied as well. Then Saul went to Ramah himself and came to the great well that is in Secu; and he asked, “Where are Samuel and David?” And he was told, “They are at Naioth [with the prophets] in Ramah.” So he went on to Naioth in Ramah; and the Spirit of God came upon him too, and he went along continually prophesying until he came to Naioth in Ramah. He also took off his [royal] robes [and armor] and prophesied before Samuel and lay down naked all that day and night. So they say, “Is Saul also among the prophets?” [1 Sam 10:10]
