'Shaft' in the Bible

There was war with the Philistines again at Gob, and Elhanan the son of Jaare-oregim the Bethlehemite killed Goliath the Gittite, the shaft of whose spear was like a weaver’s beam.

But the man who touches themMust be armed with iron and the shaft of a spear,And they will be completely burned with fire in their place.”
