'Staff' in the Bible

Let it fall on the head of Joab, and on all his father's house. Let there not fail from the house of Joab one who has an issue, or who is a leper, or who leans on a staff, or who falls by the sword, or who lacks bread."

There was again war with the Philistines at Gob; and Elhanan the son of Jaareoregim the Bethlehemite killed Goliath the Gittite's brother, the staff of whose spear was like a weaver's beam.

But the man who touches them must be armed with iron and the staff of a spear. They shall be utterly burned with fire in their place."

He killed an Egyptian, a goodly man: and the Egyptian had a spear in his hand; but he went down to him with a staff, and plucked the spear out of the Egyptian's hand, and killed him with his own spear.
