Moses officiates for God during the ceremony of consecration and ordination of Aaron and his sons into the priesthood. Moses washed Aaron and his sons with water from the bronze basin in the Tabernacle courtyard. After washing them Moses first dresses Aaron in the priestly white tunic and over that the garments worn by the high priest: the robe and the ephod. Over the ephod was place the breastpiece with the twelve precious stones that represented the twelve tribes of Israel mounted on the front. Moses place the Urim and Thumimim into the breastplate where they would be kept for the times they were removed for inquiring of the Lord. On Aaron's head Moses placed the turban with a golden plate set on the front of the turban that said, "Holy To The Lord." (Ex 28:36; 39:30)

Once Aaron was dressed as the high priest Moses anointed the tabernacle and the furniture in the tabernacle with the oil described in Exodus 30:23-25 as perfumed oil. Then Moses went into the courtyard and anointed the altar of burnt offering, the bronze basin and all the utensils used with the altar and the basin. When the tabernacle had been anointed Moses then poured some of the oil on Aaron's head to anoint and consecrate Aaron as part of the tabernacle. The short, three verse Psalm 133 refers to this moment when Aaron was anointed with the perfumed oil that was poured out on his head:

It is like precious oil poured on the head,
running down on the beard,
running down on Aaron's beard,
down on the collar of his robe. - Ps. 133:2

Next Aaron's four sons - Nadab and Abihu, Eleazar and Ithamar (Exodus 6:23) - were dressed in the garments of the priests: white tunics secured with sashes and turbans to cover their heads.

Three sacrifices were made. The first was a bull for the sin offering of Aaron and his four sons. Aaron and his sons laid their hands on the bull to identify with it and to place their sins on the bull. The bull was then slaughtered. Blood from the bull was placed on the four horns of the altar and the rest of the blood was poured at the base of the altar. The fat portions, the kidneys and the liver were burnt on the altar. But, the rest of the bull was taken outside the camp and totally incinerated.

The second was one of two rams as a burnt offering. After Aaron and his sons laid their hands on the ram, it was slaughtered and its blood was sprinkled against the side of the altar. The ram was cut and burnt as a food offering to the Lord. Some of the meat of the ram of ordination was eaten in the Tabernacle courtyard near the gate before the Lord as a symbol of the new relationship the priests, Aaron and his sons, had with the Lord.

The third sacrifice was the second of two rams, which was offered as the ram of ordination. Some of the blood of this ram was placed on the lobe of Aaron's right ear, on the thumb of Aaron's right hand and on the big toe of Aaron's right foot. The same was done to Nadab and Abihu, Eleazar and Ithamar.

"The nature of Christ’s existence is mysterious, I admit; but this mystery meets the wants of man. Reject it and the world is an inexplicable riddle – believe it; and the history of our race is satisfactorily explained."

“In as many days as this world was made, in so many thousand years will it be concluded…For the day of the Lord is as a thousand years.  In six days created things were completed. It is evident, therefore, that they will come to an end at the sixth thousand year.” – Irenaeus, 180 AD
