Exodus 29:11, 16, 20

Slaughter it in the LORD’s presence at the entrance to the tent of meeting.

Slaughter it and take the blood and splash it against the sides of the altar.

Slaughter it, take some of its blood and put it on the lobes of the right ears of Aaron and his sons, on the thumbs of their right hands, and on the big toes of their right feet. Then splash blood against the sides of the altar.
