The Lord gives a command to the priests: if they do not listen and resolve to honor his name, he will send a curse on them and on their blessings. God recalls his covenant with Levi, a covenant of life and peace that Levi honored with reverent fear. In his day true instruction was in his mouth, he walked with God in uprightness and turned many from sin. But the priests of today have turned from the way, caused many to stumble by their teaching and corrupted the covenant, so the Lord will make them despised before all the people (vv. 1-9).
The prophet then addresses the whole people: do we not all have one Father, one God who created us? Why are we faithless to one another? Judah has profaned the Lord's sanctuary by marrying the daughter of a foreign god. The Lord will cut off from the tents of Jacob anyone who does this. The people also cover the altar with tears, but God no longer accepts their offerings. They ask why, and the Lord answers that he has been witness between them and the wife of their youth, whom they betrayed though she was their companion and their wife by covenant. God says he hates divorce and violence and calls them to guard their spirit and not be faithless (vv. 10-16).
The chapter closes with a different charge: they have wearied the Lord with their words. They ask how, and he answers: when they say that everyone who does evil is good in the Lord's sight, or ask where the God of justice is (v. 17).
