Exodus 28:1-3

“Have Aaron your brother brought to you from among the Israelites, along with his sons Nadab and Abihu, Eleazar and Ithamar, so they may serve me as priests. Make sacred garments for your brother Aaron to give him dignity and honor. Tell all the skilled workers to whom I have given wisdom in such matters that they are to make garments for Aaron, for his consecration, so he may serve me as priest.
