Exodus 28:1-5

Then bring near to you Aaron your brother, and his sons with him, from among the people of Israel, to serve me as priests - Aaron and Aaron's sons, Nadab and Abihu, Eleazar and Ithamar. And you shall make holy garments for Aaron your brother, for glory and for beauty.

Our adorning under the gospel is not to be of gold and costly array, but the garments of salvation, the robe of righteousness.
