Deuteronomy 10:9-13

Wherefore Levi hath no part nor inheritance with his brethren; the LORD is his inheritance, according as the LORD thy God promised him.

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.

And the LORD said unto me, Arise, take thy journey before the people, that they may go in and possess the land, which I sware unto their fathers to give unto them.

And now, Israel, what doth the LORD thy God require of thee, but to fear the LORD thy God, to walk in all his ways, and to love him, and to serve the LORD thy God with all thy heart and with all thy soul,

To keep the commandments of the LORD, and his statutes, which I command thee this day for thy good?
