Leviticus 3:2

‘And he shall lay his hand on the head of the burnt offering, that it may be accepted for him to make atonement on his behalf.

‘Then he shall slaughter the young bull before Yahweh; and Aaron’s sons the priests shall bring near the blood and splash the blood around on the altar that is at the doorway of the tent of meeting.

and he shall lay his hand on the head of his offering and slaughter it before the tent of meeting, and Aaron’s sons shall splash its blood around on the altar.

Then he slaughtered the ox and the ram, the sacrifice of peace offerings which was for the people; and Aaron’s sons handed the blood to him, and he splashed it around on the altar.

and for the sacrifice of peace offerings, two oxen, five rams, five male goats, five male lambs one year old. This was the offering of Gamaliel the son of Pedahzur.

“But the firstborn of an ox or the firstborn of a sheep or the firstborn of a goat, you shall not redeem; they are holy. You shall splash their blood on the altar and shall offer up their fat in smoke as an offering by fire, for a soothing aroma to Yahweh.

“And you shall offer your burnt offerings, the flesh and the blood, on the altar of Yahweh your God; and the blood of your sacrifices shall be poured out on the altar of Yahweh your God, and you shall eat the flesh.
