Exodus 29:3

1“This is the thing that you shall do to them to make them holy, to minister to me in the priest’s office: take one young bull and two rams without defect,

2unleavened bread, unleavened cakes mixed with oil, and unleavened wafers anointed with oil. You shall make them of fine wheat flour.

3You shall put them into one basket, and bring them in the basket, with the bull and the two rams.

4You shall bring Aaron and his sons to the door of the Tent of Meeting, and shall wash them with water.

5You shall take the garments, and put on Aaron the tunic, the robe of the ephod, the ephod, and the breastplate, and clothe him with the skillfully woven band of the ephod.
