'Hair' in the Bible

Then the army told Saul, "Shall Jonathan die, who brought about this great deliverance in Israel? As the LORD lives, not one hair of his head will fall to the ground, because today he did this with God's help."

Then Michal took the household idol and laid it on the bed with a cover of goat hair placed at its head. Then she covered it with clothes.

The messengers went in, and there was the household idol in the bed with the cover of goat hair at its head!
