1 Samuel 21:9-10

ASV(i) 9 And the priest said, The sword of Goliath the Philistine, whom thou slewest in the vale 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.
10 And David arose, and fled that day for fear of Saul, and went to Achish the king of Gath.
