Exodus 29:21, 29

And you shall take some of the blood that is on the altar, and some of the anointing oil, and sprinkle it on Aaron and on his garments, on his sons and on the garments of his sons with him; and he and his garments shall be hallowed, and his sons and his sons’ garments with him.

“And the holy garments of Aaron shall be his sons’ after him, to be anointed in them and to be consecrated in them.
