The LORD spoke to Moses, saying,
Hitherto we have had the instructions which Moses was directed to give to the people concerning the sacrifices; but here begin the instructions he was to give to the priests; he must command Aaron and his sons, Lev 6:9. The priests were rulers in the house of God, but these rulers must be ruled; and those that had the command of others must themselves be commanded.
Commenting on Leviticus 6:8-13
And the Lord spake unto Moses,.... It maybe after some intermission, or pause made; for some here begin a new chapter, and indeed a new section here begins in the Hebrew copies: saying; as follows:
And the Lord spake unto Moses - At this verse the Jews begin the 25th section of the law; and here, undoubtedly, the 6th chapter should commence, as the writer enters upon a new subject, and the preceding verses belong to the fifth chapter. The best edited Hebrew Bibles begin the 6th chapter at this verse.
