'Weaver's' in the Bible

He also killed an Egyptian who was seven and a half feet tall. Even though the Egyptian had a spear in his hand like a weaver’s beam, Benaiah went down to him with a club, snatched the spear out of the Egyptian’s hand, and then killed him with his own spear.

Once again there was a battle with the Philistines, and Elhanan son of Jair killed Lahmi the brother of Goliath the Gittite. The shaft of his spear was like a weaver’s beam.
