The process of consecrating the priests involved a bull, two rams, and unleavened bread. All the items would be brought to the tabernacle, along with Aaron and his sons. At the door of the tabernacle, the priests would be washed with water and then dressed in the garments of the priesthood. They would then be anointed with anointing oil. After these actions, the bull would be brought before the tabernacle, the priests would put their hands on the head of the bull, and he would be killed. Blood would be taken from the bull and be put on the horns of the altar with the rest poured on the ground by the base of the altar. They were to take all the fat from the animal and burn it on the altar. The flesh would be burned outside the camp as a sin offering.
One of the rams would be killed the same way, and its blood sprinkled around the altar. The ram would be cut up, placed on the altar, and burned completely. This is a burnt offering unto the Lord. The second ram would be killed the same way, and some of its blood would be put on the tip of the right ear of the priests, the thumb and big toe of their right hand and foot, and the rest sprinkled around the altar.
The blood and anointing oil are also sprinkled on the priests and their garments. After that, the priests would be considered hallowed before God. The second ram, along with bread, would be waved before the Lord by the priests, and then given back to be burned. This is a wave offering and an offering made by fire. The breast would be the portion of the priests. It is called a heave offering.
The ram of consecration would be boiled in the holy place, and the bread in the basket would be eaten along with it when the priests enters for service. This is a consecration offering. Any of it that is left over by morning is to be burned.
The altar will be consecrated daily for seven days by sacrificing an bull, and it will be most holy. The passage then goes on to discuss what are called the daily offerings. This process would be for the consecration of the priests for service.
This process is elaborate and lengthy, but very telling about the things that are required for us to be ready for ministry. Blood sacrifices were required. The blood had to be applied to the priests. The blood represented the life force of the animal, and could not be eaten with the meat and bread. This entire process points out the need for those God will use to be covered by the blood of Jesus Christ in order to adequately serve the Kingdom of God. God is calling each of us to His service, but we must seek daily consecration (like the daily sacrifices) in order to be in the center of His will and to serve with excellence and anointing.
