Saul tells his son Jonathan and all his servants to kill David. Jonathan, who loves David, warns him to hide and then speaks well of David to his father, reminding him that David risked his life against Goliath and that killing him would be a sin against innocent blood. Saul listens and swears that David will not be put to death, and Jonathan brings David back into the king's presence.
War breaks out again and David defeats the Philistines. Then an evil spirit from the Lord comes upon Saul, and as David plays the harp Saul tries to pin him to the wall with his spear. David slips away and flees that night. Saul sends messengers to watch David's house and kill him in the morning, but Michal warns her husband, lets him down through a window and puts a household idol in the bed with a covering of goat's hair. When the messengers come she says David is sick, and when Saul orders him brought in the bed, the trick is discovered. Michal tells her father that David threatened her.
David escapes and comes to Samuel at Ramah and tells him everything. They go to live at Naioth. Saul sends messengers, but they see the prophets prophesying with Samuel leading them, and the Spirit of God comes on them so that they prophesy too. The same happens to two more groups. Finally Saul goes himself; the Spirit of God comes upon him, he walks along prophesying, strips off his clothes and lies down all that day and night.
