7:21 Put - Ironical words, take those that are peculiar, and to be all burnt to me, and do what you will with them, I will have none of them. To your sacrifices - That part of your sacrifices, which you are allowed to eat, they are but as profane food.
7:21-28 God shows that obedience was required of them. That which God commanded was, Hearken diligently to the voice of the Lord thy God. The promise is very encouraging. Let God's will be your rule, and his favour shall be your happiness. God was displeased with disobedience. We understand the gospel as little as the Jews understood the law, if we think that even the sacrifice of Christ lessens our obligation to obey.
