David went to the Philistine city of Gath to escape from Saul. But the people there thought they recognized him as a notorious Philistine slaughterer. So David pretended he was insane, and then he ran away and hid in a cave.

Then he went into a city and fought the Philistines who were attacking it. But God told him that Saul was coming, and that the people of the city would hand him over to Saul to keep him from destroying their city. So David left the city, and what God predicted didn’t happen.
