8. At that time This expression is to be understood, not as referring to the time subsequent to the death of Aaron, but as in the first verse of this chapter and in Deuteronomy 9:20, to the time when the covenant was renewed on Sinai. The apostasy of the people when the golden calf was made and worshipped is present to the mind of the speaker. The tribe of Levi, the great lawgiver’s own tribe, showed their fidelity to him. “Then Moses stood in the gate of the camp and said, Who is on the Lord’s side? Let him come unto me. And all the sons of Levi gathered themselves together unto him.” Exodus 32:26. The tribe of Levi was set apart for special service connected with worship and sacrifice. It is evident from Numbers 4:4, and following verses, that the office of carrying the ark on the march devolved on the non-priestly Levites, namely, the Kohathites, but on some special occasions it was borne by the priests. See Joshua 3:3; Joshua 3:6; Joshua 3:8; also Deuteronomy 6:6, and 1 Kings 8:3. Comp. Deuteronomy 31:9, of this book.
