1 Samuel 19:15-24 CJB

15 Sha'ul sent the messengers to see David with the order, "Bring him up to me, bed and all, so that I can kill him."
16 But when the messengers entered, there before them was the household idol in the bed, with the goat's-hair quilt at its head.
17 Sha'ul asked Mikhal, "Why did you deceive me this way and let my enemy go and escape?" Mikhal answered Sha'ul, "He threatened me, 'Let me go, or I'll kill you.'"
18 David fled and escaped, then came to Sh'mu'el in Ramah and told him everything Sha'ul had done to him. So he and Sh'mu'el went and stayed in the prophets'dormitory.
19 The news reached Sha'ul that David had been seen at the prophets'dormitory in Ramah.
20 Sha'ul sent messengers to capture David. But when they saw the group of prophets prophesying, with Sh'mu'el standing and leading them, the Spirit of God fell on Sha'ul's messengers; and they too began prophesying.
21 When Sha'ul was told, he sent other messengers; but they too began prophesying. Sha'ul sent messengers a third time, and they also prophesied.
22 Then he himself went to Ramah. When he arrived at the big cistern in Sekhu, he asked, "Where are Sh'mu'el and David?" Someone answered, "They're at the prophets' dormitory in Ramah."
23 While on his way to the prophets' dormitory in Ramah, the Spirit of God fell on him too; and he went on, prophesying, until he arrived at the prophets' dormitory in Ramah.
24 He also stripped off his clothes, prophesied in Sh'mu'el's presence and lay there naked all that day and all that night. Hence it continues to be an expression, "Is Sha'ul a prophet, too?"
