And he said unto Aaron, Take thee a young calf for a sin offering, and a ram for a burnt offering, without blemish, and offer them before the LORD.

And unto the children of Israel thou shalt speak, saying, Take ye a kid of the goats for a sin offering; and a calf and a lamb, both of the first year, without blemish, for a burnt offering;

Aaron therefore went unto the altar, and slew the calf of the sin offering, which was for himself.

When a calf or lamb, or goat, shall be brought forth, it shall be seven days under its mother; and from the eighth day and beyond, it shall be accepted for an offering, a sacrifice to Jehovah.
