Exodus 28:41-43

The Voice

⁴¹ When they serve as priests, dress Aaron, your brother, and his sons in these ceremonial garments; anoint them, ordain them, and consecrate them. ⁴² Furnish them with linen undergarments, so that they are covered from their waists to their thighs. ⁴³ Aaron and his sons are to put them on whenever they go into the congregation tent or go near the altar to minister in the holy place. They must do this so that they don’t incur guilt and die. This directive stands forever for Aaron and all those who come after him.
