Exodus 29:7

“You shall put them on Aaron your brother and on his sons with him; and you shall anoint them and ordain them and set them apart as holy, that they may minister to Me as priests.

“And you shall anoint Aaron and his sons, and you shall set them apart as holy, that they may minister as priests to Me.

Then he poured some of the anointing oil on Aaron’s head and anointed him, to set him apart as holy.

nor shall he go out of the sanctuary nor profane the sanctuary of his God, for the dedication of the anointing oil of his God is on him; I am Yahweh.

It is like the good oil upon the head, Coming down upon the beard, Aaron’s beard, Coming down upon the edge of his robes.

“When the priests enter, then they shall not go out into the outer court from the sanctuary without laying there their garments in which they minister, for they are holy. They shall put on other garments; then they shall come near to that which is for the people.”

Then he said, “These are the two anointed ones who are standing by the Lord of all the earth.”
