Exodus 29:6-16

6 Put the turban on him and tie on it the sacred sign of dedication engraved "Dedicated to the Lord.'
7 Then take the anointing oil, pour it on his head, and anoint him.
8 "Bring his sons and put shirts on them;
9 put sashes around their waists and tie caps on their heads. That is how you are to ordain Aaron and his sons. They and their descendants are to serve me as priests forever.
10 "Bring the bull to the front of the Tent of my presence and tell Aaron and his sons to put their hands on its head.
11 Kill the bull there in my holy presence at the entrance of the Tent.
12 Take some of the bull's blood and with your finger put it on the projections of the altar. Then pour out the rest of the blood at the base of the altar.
13 Next, take all the fat which covers the internal organs, the best part of the liver, and the two kidneys with the fat on them, and burn them on the altar as an offering to me.
14 But burn the bull's flesh, its skin, and its intestines outside the camp. This is an offering to take away the sins of the priests.
15 "Take one of the rams and tell Aaron and his sons to put their hands on its head.
16 Kill it, and take its blood and throw it against all four sides of the altar.
