17:2And Saul and the men of Israel were gathered together, and pitched by the valley of Elah, and set the battle in array against the Philistines.

21:9And 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.
