Exodus 29:11

‘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.

‘Then he shall lay his hand on the head of his offering and slaughter it at the doorway of the tent of meeting, and Aaron’s sons the priests shall splash the blood around on the altar.

“Next he shall slaughter the male lamb in the place where they slaughter the sin offering and the burnt offering, at the place of the sanctuary—for the guilt offering, like the sin offering, belongs to the priest; it is most holy.
