7 He put the tunic on Aaron, tied the sash around him, clothed him with the robe and put the ephod on him. He also fastened the ephod with a decorative waistband, which he tied around him.

30 Then Moses took some of the anointing oil and some of the blood from the altar and sprinkled them on Aaron and his garments and on his sons and their garments. So he consecrated Aaron and his garments and his sons and their garments.
