Malachi is used to show that Israel returned from exile but drifted back into self-focused living, especially the priests who should’ve led people to honor God. The passage highlights two connected sins—marrying into idolatry and then divorcing their covenant wives to do it—saying this “treachery” breaks God’s design for a holy people, harms families, and even makes their worship unacceptable because God cares deeply how they treat their spouses and keep their marriage covenant.
