'Hair' in the Bible

Cut off the hair of your sacred vow and throw it away. Raise up a dirge on the barren heights, for the Lord has rejected and abandoned the generation under His wrath.

Egypt, Judah, Edom, the Ammonites, Moab, and all the inhabitants of the desert who clip the hair on their temples. All these nations are uncircumcised, and the whole house of Israel is uncircumcised in heart.”
