Exodus 29:1-4

1“This is what you are to do for them to consecrate them to serve me as priests. Take a young bull and two unblemished rams,

2with unleavened bread, unleavened cakes mixed with oil, and unleavened wafers coated with oil. Make them out of fine wheat flour,

3put them in a basket, and bring them in the basket, along with the bull and two rams.

4Bring Aaron and his sons to the entrance to the tent of meeting and wash them with water.
