1“Now this is what you are to do to consecrate Aaron and his sons to serve Me as priests: Take a young bull and two rams without blemish,
2along with unleavened bread, unleavened cakes mixed with oil, and unleavened wafers anointed with oil. Make them out of fine wheat flour,
3put them in a basket, and present them in the basket, along with the bull and the two rams.
4Then present Aaron and his sons at the entrance to the Tent of Meeting and wash them with water.
— Exodus 29:1-4
