'Hair' in the Bible

‘Cut off your hair [your crown, O Jerusalem] and throw it away,And take up a mournful cry on the barren heights,For the Lord has rejected and abandonedThe generation of His wrath.’

Egypt and Judah, and Edom and the sons of Ammon, and Moab and all those who live in the desert who clip off the hair on their temples; for all these nations are uncircumcised (sinful, impure), and all the house of Israel are uncircumcised in heart.”

Dedan, Tema, Buz [the neighboring tribes north of Arabia], and all who clip off the side-growth of their hair;

“Their camels will become plunder,And their herds of cattle a spoil;And I will scatter to all the [four] winds those who cut the corners of their hair [as evidence of their idolatry],And I will bring their disaster from every side,” says the Lord.
