Saul sent the agents [back] to see David and said, "Bring him on his bed so I can kill him."
When the messengers arrived, to their surprise, the household idol was on the bed with some goats' hair on its head.
Saul asked Michal, "Why did you deceive me like this? You sent my enemy away, and he has escaped!" She answered him, "He said to me, 'Let me go! Why should I kill you?' "
So David fled and escaped and went to Samuel at Ramah and told him everything Saul had done to him. Then he and Samuel left and stayed at Naioth.
When it was reported to Saul that David was at Naioth in Ramah,
Saul sent agents to seize David. However, when they saw the group of prophets prophesying with Samuel leading them, the Spirit of God came on Saul's agents, and they also started prophesying.
When they reported to Saul, he sent other agents, and they also began prophesying. So Saul tried again and sent a third group of agents, and even they began prophesying.
Then Saul himself went to Ramah. He came to the large cistern at Secu, looked around, and asked, "Where are Samuel and David?" "At Naioth in Ramah," someone said.
So he went to Naioth in Ramah. The Spirit of God also came on him, and as he walked along, he prophesied until he entered Naioth in Ramah.
Saul then removed his clothes and also prophesied before Samuel; he collapsed [and lay] naked all that day and all that night. That is why they say, "Is Saul also among the prophets?"
