Make sacral vestments for your brother Aaron, for dignity and adornment.
Exodus 28:2
Then bring his sons forward; clothe them with tunics and wind turbans upon them. And gird both Aaron and his sons with sashes. And so they shall have priesthood as their right for all time.
Exodus 29:8-9
You shall then ordain Aaron and his sons.
Then Moses brought Aaron and his sons forward and washed them with water. He put the tunic on him, girded him with the sash, clothed him with the robe, and put the ephod on him, girding him with the decorated band with which he tied it to him. He put the breastpiece on him, and put into the breastpiece the Urim and Thummim. And he set the headdress on his head; and on the headdress, in front, he put the gold frontlet, the holy diadem—as the LORD had commanded Moses.
Leviticus 8:6-9
