Exodus 28:42-43

GOD’S WORD Translation

⁴² “Make linen undergarments to cover them down to their thighs. ⁴³ Aaron and his sons must wear them when they go into the tent of meeting or when they come near the altar to serve as priests in the holy place. Then they will be blameless and won’t die.

“This is a permanent law for him and his descendants.”
