These verses are closely connected with the preceding chapter, and state very briefly the results of the intercession of Moses recorded in Deuteronomy 9:25-29. The people are reminded that all their blessings and privileges, forfeited by apostasy as soon as bestowed, were only now their own by a new and most unmerited act of grace on the part of God, won from Him by the self-sacrificing mediation of Moses himself Deuteronomy 10:10.
Deuteronomy 10:1-5. The order for making the ark and tabernacle was evidently given before the apostasy of the people (Exo. 25ff); but the tables were not put in the ark until the completion and dedication of the tabernacle Exodus 40. But here as elsewhere (compare the Deuteronomy 9:1 note) Moses connects transactions closely related to each other and to his purpose without regard to the order of occurrence.
There Aaron died - i. e., while the people were encamped in Mosera or Moseroth. In Deuteronomy 32:50; as well as in Numbers 20:25 ff Mount Hor is assigned as the place of Aaron’s death. It is plain then that Moserah was in the neighborhood of Mount Hor. The appointment of Eleazar to minister in place of Aaron, is referred to as a proof of the completeness and fulness of the reconciliation effected between God and the people by Moses. Though Aaron was sentenced to die in the wilderness for his sin at Meribah, yet God provided for the perpetuation of the high priesthood, so that the people would not suffer. Compare Deuteronomy 9:20 and note.
At that time - i. e., that of the encampment at Sinai, as the words also import in Deuteronomy 10:1. Throughout the passage the time of the important events at Sinai is kept in view; it is reverted to as each incident is brought forward by Moses, alluded to sufficiently for his purpose, and dismissed.
Moses is evidently here speaking of the election by God of the tribe of Levi at large, priests and others also, for His own service.
