'Weaver's' in the Bible

And he himself struck down an Egyptian man, a large man five cubits [tall]. And in the hand of the Egyptian [was] a spear like a weaver's beam. But he went down to him with a club and seized the spear from the hand of the Egyptian and killed him with his own spear.

And again there was war with the Philistines. And Elhanan son of Jair struck down Lahmi, the brother of Goliath the Gittite, the shaft of whose spear [was] like a weaver's beam.
