Leviticus 1:1-4

And Jehovah called unto Moses, and spake unto him out of the tent of meeting, saying, Speak unto the children of Israel, and say unto them, When any man of you offereth an oblation unto Jehovah, ye shall offer your oblation of the cattle, even of the herd and of the flock. If his oblation be a burnt-offering of the herd, he shall offer it a male without blemish: he shall offer it at the door of the tent of meeting, that he may be accepted before Jehovah. And he shall lay his hand upon the head of the burnt-offering; and it shall be accepted for him to make atonement for him.
