Exodus 29:9-11

Amplified Bible, Classic Edition

⁹ And you shall gird them with sashes or belts, Aaron and his sons, and bind caps on them; and the priest’s office shall be theirs by a perpetual statute. Thus you shall ordain and consecrate Aaron and his sons.

¹¹ And you shall kill the bull before the Lord by the door of the Tent of Meeting.
