Summary
In verses 1‑2 the Lord declares that a messenger of the covenant will prepare the way for His return, likening the Lord’s coming to a refiner’s fire. Verses 3‑4 describe the messenger purifying the Levitical priesthood and restoring sincere offerings so that Judah’s worship will again please God. Verses 5‑11 contain a stern judgment against sorcerers, adulterers, liars, and social wrongdoers, accompanied by a call to return to God’s ordinances—especially the tithes and offerings—so that He will open the “windows of heaven” and protect the land. Verses 12‑14 lament Israel’s pride and false sense of self‑sufficiency, while verses 15‑17 highlight that the truly fearful will be recorded in a book of remembrance and spared by God. Finally, verse 18 promises that in the day of judgment God will distinguish the righteous from the wicked and reward those who serve Him.
