Hebrews 5:3

And thou shalt take of the blood of the bullock, and put it upon the horns of the altar with thy finger, and pour all the blood beside the bottom of the altar. And thou shalt take all the fat that covereth the inwards, and the caul that is above the liver, and the two kidneys, and the fat that is upon them, and burn them upon the altar. But the flesh of the bullock, and his skin, and his dung, shalt thou burn with fire without the camp: it is a sin offering. Thou shalt also take one ram; and Aaron and his sons shall put their hands upon the head of the ram. And thou shalt slay the ram, and thou shalt take his blood, and sprinkle it round about upon the altar. And thou shalt cut the ram in pieces, and wash the inwards of him, and his legs, and put them unto his pieces, and unto his head. And thou shalt burn the whole ram upon the altar: it is a burnt offering unto the LORD: it is a sweet savor, an offering made by fire unto the LORD. And thou shalt take the other ram; and Aaron and his sons shall put their hands upon the head of the ram.

If 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. And he shall bring the bullock unto the door of the tabernacle of the congregation before the LORD; and shall lay his hand upon the bullock's head, and kill the bullock before the LORD. And the priest that is anointed shall take of the bullock's blood, and bring it to the tabernacle of the congregation: And the priest shall dip his finger in the blood, and sprinkle of the blood seven times before the LORD, before the vail of the sanctuary. And the priest shall put some of the blood upon the horns of the altar of sweet incense before the LORD, which is in the tabernacle of the congregation; and shall pour all the blood of the bullock at the bottom of the altar of the burnt offering, which is at the door of the tabernacle of the congregation. And he shall take off from it all the fat of the bullock for the sin offering; the fat that covereth the inwards, and all the fat that is upon the inwards, And the two kidneys, and the fat that is upon them, which is by the flanks, and the caul above the liver, with the kidneys, it shall he take away, As it was taken off from the bullock of the sacrifice of peace offerings: and the priest shall burn them upon the altar of the burnt offering. And the skin of the bullock, and all his flesh, with his head, and with his legs, and his inwards, and his dung, Even the whole bullock shall he carry forth without the camp unto a clean place, where the ashes are poured out, and burn him on the wood with fire: where the ashes are poured out shall he be burnt.

And he brought the bullock for the sin offering: and Aaron and his sons laid their hands upon the head of the bullock for the sin offering. And he slew it; and Moses took the blood, and put it upon the horns of the altar round about with his finger, and purified the altar, and poured the blood at the bottom of the altar, and sanctified it, to make reconciliation upon it. And he took all the fat that was upon the inwards, and the caul above the liver, and the two kidneys, and their fat, and Moses burned it upon the altar. But the bullock, and his hide, his flesh, and his dung, he burnt with fire without the camp; as the LORD commanded Moses. And he brought the ram for the burnt offering: and Aaron and his sons laid their hands upon the head of the ram. And he killed it; and Moses sprinkled the blood upon the altar round about. And he cut the ram into pieces; and Moses burnt the head, and the pieces, and the fat. And he washed the inwards and the legs in water; and Moses burnt the whole ram upon the altar: it was a burnt sacrifice for a sweet savor, and an offering made by fire unto the LORD; as the LORD commanded Moses.

And Moses said unto Aaron, Go unto the altar, and offer thy sin offering, and thy burnt offering, and make an atonement for thyself, and for the people: and offer the offering of the people, and make an atonement for them; as the LORD commanded.

And Aaron shall offer his bullock of the sin offering, which is for himself, and make an atonement for himself, and for his house.

Who needeth not daily, as those high priests, to offer up sacrifice, first for his own sins, and then for the people's: for this he did once, when he offered up himself.

But into the second went the high priest alone once every year, not without blood, which he offered for himself, and for the errors of the people:
