1 Samuel 21:6-9

6So the priest gave him the holy bread, for there was no bread there but the bread of the Presence, which is removed from before the Lord, to be replaced by hot bread on the day it is taken away.

7Now a certain man of the servants of Saul was there that day, detained before the Lord. His name was Doeg the Edomite, the chief of Saul's herdsmen.

8Then David said to Ahimelech, "Then have you not here a spear or a sword at hand? For I have brought neither my sword nor my weapons with me, because the king's business required haste."

9And the priest said, "The sword of Goliath the Philistine, whom you struck down in the Valley of Elah, behold, it is here wrapped in a cloth behind the ephod. If you will take that, take it, for there is none but that here." And David said, "There is none like that; give it to me."
