1 Samuel 21:8-9

8And David said to Ahimelech, And is there not here under thy hand spear or sword? for I have neither brought my sword nor my weapons with me, for the king's business was urgent.

9And the priest said, The sword of Goliath the Philistine, whom thou slewest in the valley of terebinths, 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.
