Ezekiel 44:15; Ezekiel 44:18

15 “ ‘But the Levitical priests, who are descendants of Zadok and who guarded my sanctuary when the Israelites went astray from me, are to come near to minister before me; they are to stand before me to offer sacrifices of fat and blood, declares the Sovereign LORD.

18 They are to wear linen turbans on their heads and linen undergarments around their waists. They must not wear anything that makes them perspire.
