Exodus 29:35-37

New Century Version

³⁵ “Do all these things that I commanded you to do to Aaron and his sons, and spend seven days appointing them. ³⁶ Each day you are to offer a bull to remove the sins of Aaron and his sons so they will be given for service to the Lord. Make the altar ready for service to the Lord, and pour oil on it to make it holy. ³⁷ Spend seven days making the altar ready for service to God and making it holy. Then the altar will become very holy, and anything that touches it must be holy.
