Exodus 29:9 (KJV)

And Aaron and his sons thou shalt bring unto the door of the tabernacle of the congregation, and shalt wash them with water.

And thou shalt take the garments, and put upon Aaron the coat, and the robe of the ephod, and the ephod, and the breastplate, and gird him with the curious girdle of the ephod:

And thou shalt put the mitre upon his head, and put the holy crown upon the mitre.

Then shalt thou take the anointing oil, and pour it upon his head, and anoint him.

And thou shalt bring his sons, and put coats upon them.

And thou shalt cause a bullock to be brought before the tabernacle of the congregation: and Aaron and his sons shall put their hands upon the head of the bullock.

And thou shalt kill the bullock before the LORD, by the door of the tabernacle of the congregation.

And thou shalt take of the blood of the bullock, and put it upon the horns of the altar with thy finger, and pour all the blood beside the bottom of the altar.

And thou shalt take all the fat that covereth the inwards, and the caul that is above the liver, and the two kidneys, and the fat that is upon them, and burn them upon the altar.

But the flesh of the bullock, and his skin, and his dung, shalt thou burn with fire without the camp: it is a sin offering.
