1 Samuel 21:10 KJV

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.

10And David arose, and fled that day for fear of Saul, and went to Achish the king of Gath.

11And the servants of Achish said unto him, Is not this David the king of the land? did they not sing one to another of him in dances, saying, Saul hath slain his thousands, and David his ten thousands?

12And David laid up these words in his heart, and was sore afraid of Achish the king of Gath.
