Leviticus 3:1-2

¹“Also tell the people, ‘When the offering that you bring to Yahweh is to maintain good fellowship with him, you may bring a bull or a cow from your herd of cattle, but what you present to Yahweh must be an animal that has no defects.

²You must bring the animal to the entrance to the Sacred Tent. You must lay your hands on its head. Then you must slaughter it and drain some of its blood in a bowl. Then one of Aaron's sons, one of the priests, will sprinkle the blood against all sides of the altar.
