Lev 4.3If the priest that is anointed do sin according to the sin of the people; then let him bring for his sin, which he hath sinned, a young bullock without blemish unto the LORD for a sin offering.
Ex 29.25And thou shalt receive them of their hands, and burn them upon the altar for a burnt offering, for a sweet savor before the LORD: it is an offering made by fire unto the LORD.
