Exodus 28:1, 4

“Then bring near to yourself Aaron your brother, and his sons with him, from among the sons of Israel, to minister as priest to Me—Aaron, Nadab and Abihu, Eleazar and Ithamar, Aaron’s sons.

These are the garments which they shall make: a breastpiece and an ephod and a robe and a tunic of checkered work, a turban and a sash, and they shall make holy garments for Aaron your brother and his sons, that he may minister as priest to Me.
