Numbers 18:1-2

Wycliffe Bible

18 And the Lord said to Aaron, Thou, and thy sons, and the house of thy father with thee, shall bear the wickedness of the saintuary; and thou and thy sons together shall suffer the sins of your priesthood (but only thou and thy sons shall bear the sins of your priesthood).

² But also take thou with thee thy brethren of the lineage of Levi, and the sceptre, or power, of thy father, and be they ready, that they minister to thee. Forsooth thou and thy sons shall minister in the tabernacle of witnessing; (And also take with thee thy brothers from the tribe of Levi, thy father’s tribe, and be they ready to serve thee. But thou and thy sons shall minister in the Tabernacle of the Witnessing;)
