'Rod' in the Bible

And he hath smitten the man, the Egyptian -- a man of measure, five by the cubit -- and in the hand of the Egyptian is a spear like a beam of weavers, and he goeth down unto him with a rod, and taketh violently away the spear out of the hand of the Egyptian, and slayeth him with his own spear.

And again there was war with the Philistines; and Elhanan, the son of Jair, put to death Lahmi, the brother of Goliath the Gittite, the stem of whose spear was like a cloth-worker's rod.
