Then God told Moses to begin Aaron’s ordination as priest, together with Aaron’s sons. Moses brought the vestments, anointing oil, a bull for the purgation offering, two rams, and a basket of unleavened bread, and he assembled the whole community at the entrance of the Tent of Meeting. “This is what God has commanded,” Moses said.
Moses washed Aaron with water and dressed him in the priestly garments: tunic, sash, robe, ephod, breastpiece (with the Urim and Thummim inside), and a headdress with a gold frontlet. He anointed the Tabernacle and its items, sprinkled the altar, and poured oil on Aaron’s head. Aaron’s sons were dressed in tunics, sashes, and turbans.
Offerings followed: the bull’s blood was put on the altar’s horns and poured at its base; a ram was burned as a burnt offering; and the ram of ordination was offered. Moses placed blood on the right ear, thumb, and big toe of Aaron and his sons, and he sprinkled them with oil and blood. They stayed at the entrance for seven days, eating the ordination food there and keeping God’s charge day and night.
