Leviticus 8:7; Leviticus 8:13

7 He put the tunic on him and girded him with the sash, and clothed him with the robe and put the ephod on him; and he girded him with the artistic band of the ephod, with which he tied it to him.

13 Next Moses had Aaron's sons come near and clothed them with tunics, and girded them with sashes and bound caps on them, just as the LORD had commanded Moses.
