Deuteronomy 10:8-10

Authorized (King James) Version

⁸ At that time the Lord separated the tribe of Levi, to bear the ark of the covenant of the Lord, to stand before the Lord to minister unto him, and to bless in his name, unto this day. ⁹ Wherefore Levi hath no part nor inheritance with his brethren; the Lord is his inheritance, according as the Lord thy God promised him. ¹⁰ And I stayed in the mount, according to the first time, forty days and forty nights; and the Lord hearkened unto me at that time also, and the Lord would not destroy thee.
