Leviticus 8:7

“You shall make holy garments for Aaron your brother, for glory and for beauty.

“They shall also make the ephod of gold, of blue and purple and scarlet material and fine twisted linen, the work of the skillful designer.

“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.

“Now this is what you shall do to them to set them apart as holy to minister as priests to Me: take one bull from the herd and two rams without blemish,

“And you shall take the garments, and put on Aaron the tunic and the robe of the ephod and the ephod and the breastpiece, and gird him with the skillfully woven band of the ephod;

“You shall gird them with sashes, Aaron and his sons, and bind caps on them, and they shall have the priesthood by a perpetual statute. So you shall ordain Aaron and his sons.

‘And did I not choose them from all the tribes of Israel to be My priests, to go up to My altar, to burn incense, to carry an ephod before Me; and did I not give to the house of your father all the fire offerings of the sons of Israel?

Moses and Aaron were among His priests, And Samuel was among those who called on His name; They would call upon Yahweh and He would answer them.

“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.”
