1 Samuel 21:6-9

6So the priest gave him hallowed bread: for there was no bread there but the shewbread, that was taken from before the Lord, to put hot bread in the day when it was taken away. 7Now a certain man of the servants of Saul was there that day, detained before the Lord; and his name was Doeg, an Edomite, the chiefest of the herdmen that belonged to Saul.

8And David said unto Ahimelech, And is there not here under thine hand spear or sword? for I have neither brought 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 thou slewest in the valley of Elah, behold, it is here wrapped in a cloth behind the ephod: if thou wilt take that, take it: for there is no other save that here. And David said, There is none like that; give it me.
