'Weaver's' in the Bible

And the shaft of his spear was like a weaver's beam; and his spear's head weighed six hundred shekels of iron; and the shield-bearer went before him.

And there was again a battle at Gob with the Philistines; and Elhanan the son of Jaare-oregim, a Bethlehemite, smote Goliath the Gittite; now the shaft of his spear was like a weaver's beam.

He also smote the Egyptian, a man of stature, five cubits high: and in the Egyptian's hand was a spear like a weaver's beam; and he went down to him with a staff, and plucked the spear out of the Egyptian's hand, and slew him with his own spear.

And there was again a battle with the Philistines; and Elhanan the son of Jair smote Lahmi the brother of Goliath the Gittite; now the shaft of his spear was like a weaver's beam.

My days are swifter than a weaver's shuttle, and are spent without hope.
