10 David ran away from Saul that day and went to Achish, king of Gath.21:10. Gath was a Philistine town.
11 But Achish’s officials asked the king, "Isn’t this David, the king of that country? Didn’t they sing about him in their dances, ‘Saul has killed his thousands, and David his tens of thousands’?"
12 David listened carefully to what they said and this made him very afraid of Achish, the king of Gath. 13 So he changed the way he acted toward them and pretended to be crazy. He scratched marks on the town gates and let his spit run down his beard.
