Leviticus 1:4-6

4 And he is to put his hand on the head of the burned offering and it will be taken for him, to take away his sin.

5 And the ox is to be put to death before the Lord: then Aaron's sons, the priests, are to take the blood and put some of it on and round the altar which is at the door of the Tent of meeting.

6 And the burned offering is to be skinned and cut up into its parts.
