Leviticus 3:1-2

1And if his offering be a sacrifice of peace-offering, — if he present [it] of the herd, whether a male or female, he shall present it without blemish before Jehovah.

2And he shall lay his hand on the head of his offering, and slaughter it at the entrance of the tent of meeting; and Aaron's sons, the priests, shall sprinkle the blood on the altar round about.
