Leviticus 16:3-4Christian Standard Bible (CSB)
3 “Aaron is to enter the most holy place in this way: with a young bull for a sin offering and a ram for a burnt offering. 4 He is to wear a holy linen tunic, and linen undergarments are to be on his body. He is to tie a linen sash around him and wrap his head with a linen turban. These are holy garments; he must bathe his body with water before he wears them.
