Leviticus 1:8
And the priests, Aaron’s sons, shall lay the parts, the head, and the fat, in order upon the wood that is on the fire which is upon the altar: And the priests, Aaron’s sons, shall lay the parts, the head, and the fat, in order upon the wood that is on the fire which is upon the altar:
The priests, Aaron's sons, were to place the head and the fat together with the remaining pieces of the sacrificial animal in orderly arrangement on the wood over the fire on the altar. This laying on of the offering was not mere outward ritual, for it represented the ministry and death of Christ as the Savior who would bear the sins of the world. The whole ceremonial system was appointed to point forward to Christ, with its forms to find fulfillment when type met antitype in His death.
