1 Samuel 21:6-10

6 So the priest gave him the consecrated bread, since there was no bread there except the bread of the Presence that had been removed from before the LORD and replaced by hot bread on the day it was taken away.
7 Now one of Saul’s servants was there that day, detained before the LORD; he was Doeg the Edomite, Saul’s chief shepherd.
8 David asked Ahimelek, “Don’t you have a spear or a sword here? I haven’t brought my sword or any other weapon, because the king’s mission was urgent.”
9 The priest replied, “The sword of Goliath the Philistine, whom you killed in the Valley of Elah, is here; it is wrapped in a cloth behind the ephod. If you want it, take it; there is no sword here but that one.” David said, “There is none like it; give it to me.”

David at Gath

10 That day David fled from Saul and went to Achish king of Gath.
