In the Old Testament, priests burned the sacrifices of burnt offerings to offer fire to God. (Lev 1:9, 13, 17)
Lev 1:9 But his inwards and his legs shall he wash in water: and the priest shall burn all on the altar, to be a burnt sacrifice, an offering made by fire, of a sweet savour unto the Lord. 13 But he shall wash the inwards and the legs with water: and the priest shall bring it all, and burn it upon the altar: it is a burnt sacrifice, an offering made by fire, of a sweet savour unto the Lord. 17 And he shall cleave it with the wings thereof, but shall not divide it asunder: and the priest shall burn it upon the altar, upon the wood that is upon the fire: it is a burnt sacrifice, an offering made by fire, of a sweet savour unto the Lord.
n the Old Testament, when the priest laid his hands on the head of the burnt offering, the sins of the people of Israel were imputed to the burnt offering. The priest burned the burnt offering and made a sacrifice to God. (Lev 1:4-9)
Lev 1:4 And he shall put his hand upon the head of the burnt offering; and it shall be accepted for him to make atonement for him. 5 And he shall kill the bullock before the Lord: and the priests, Aaron's sons, shall bring the blood, and sprinkle the blood round about upon the altar that is by the door of the tabernacle of the congregation. 6 And he shall flay the burnt offering, and cut it into his pieces. 7 And the sons of Aaron the priest shall put fire upon the altar, and lay the wood in order upon the fire: 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: 9 But his inwards and his legs shall he wash in water: and the priest shall burn all on the altar, to be a burnt sacrifice, an offering made by fire, of a sweet savour unto the Lord.
