Numbers 7:9-11

King James Version

⁹ But unto the sons of Kohath he gave none: because the service of the sanctuary belonging unto them was that they should bear upon their shoulders.

¹⁰ And the princes offered for dedicating of the altar in the day that it was anointed, even the princes offered their offering before the altar.

¹¹ And the Lord said unto Moses, They shall offer their offering, each prince on his day, for the dedicating of the altar.
