Ulangan 10:8

10:8 At that time the Lord set apart the tribe of Levi ¹  to carry the ark of the Lord’s covenant, to stand before the Lord to serve him, and to formulate blessings ²  in his name, as they do to this very day.

Ulangan 31:9

The Deposit of the Covenant Text

31:9 Then Moses wrote down this law and gave it to the Levitical priests, who carry the ark of the Lord’s covenant, and to all Israel’s elders.

[10:8]  ¹ sn The Lord set apart the tribe of Levi. This was not the initial commissioning of the tribe of Levi to this ministry (cf. Num 3:11-13; 8:12-26), but with Aaron’s death it seemed appropriate to Moses to reiterate Levi’s responsibilities. There is no reference in the Book of Numbers to this having been done, but the account of Eleazar’s succession to the priesthood there (Num 20:25-28) would provide a setting for this to have occurred.

[10:8]  ² sn To formulate blessings. The most famous example of this is the priestly “blessing formula” of Num 6:24-26.
