Deuteronomy 10:8-9

New King James Version

⁸ At that time ^(A)the Lord ^[a]separated the tribe of Levi ^(B)to bear the ark of the covenant of the Lord, ^(C)to stand before the Lord to minister to Him and ^(D)to bless in His name, to this day. ^9 (E)Therefore Levi has no portion nor inheritance with his brethren; the Lord is his inheritance, just as the Lord your God promised him.)
