Deuteronomy 10:8-10

World English Bible

⁸ At that time Yahweh set apart the tribe of Levi to bear the ark of Yahweh’s covenant, to stand before Yahweh to minister to him, and to bless in his name, to this day. ⁹ Therefore Levi has no portion nor inheritance with his brothers; Yahweh is his inheritance, according as Yahweh your God spoke to him.)

¹⁰ I stayed on the mountain, as at the first time, forty days and forty nights; and Yahweh listened to me that time also. Yahweh would not destroy you.
