Exodus 29:8

5 Take the robes, and put the coat and the dress and the ephod and the priest's bag on Aaron; put the band of needlework round him,

6 And let the head-dress be placed on his head and the holy crown on the head-dress.

7 Then take the oil and put it on his head.

8 And take his sons and put their robes on them;

9 And put the linen bands round Aaron and his sons, and the head-dresses on them, to make them priests by my order for ever: so you are to make Aaron and his sons holy to me.

10 Then let the ox be taken in front of the Tent of meeting: and let Aaron and his sons put their hands on its head.

11 And you are to put the ox to death before the Lord at the door of the Tent of meeting.
