Exodus 28:1, 4

“Tell your brother Aaron to come to you, along with his sons Nadab, Abihu, Eleazar, and Ithamar. Separate them from the other Israelites to serve me as priests.

These are the clothes they must make: a chest covering, a holy vest, an outer robe, a woven inner robe, a turban, and a cloth belt. The craftsmen must make these holy clothes for your brother Aaron and his sons. Then they may serve me as priests.
