Deuteronomy 10:8-10

Darby Translation

⁸ At that time Jehovah separated the tribe of Levi, to bear the ark of the covenant of Jehovah, to stand before Jehovah to do service unto him, and to bless in his name, unto this day.

⁹ Therefore Levi has no portion nor inheritance with his brethren; Jehovah is his inheritance, according as Jehovah thy God told him.

¹⁰ But I stood upon the mountain according to the former days, forty days and forty nights; and Jehovah listened unto me also at that time: Jehovah would not destroy thee.
