3:3 He will act like a refiner and purifier of silver and will cleanse the Levites and refine them like gold and silver. Then they will offer the Lord a proper offering.
Malachi 3:17
3:17 “They will belong to me,” says the Lord who rules over all, “in the day when I prepare my own special property. 1 I will spare them as a man spares his son who serves him.
Malachi 4:3
4:3 You will trample on the wicked, for they will be like ashes under the soles of your feet on the day which I am preparing,” says the Lord who rules over all.
1 sn The Hebrew word סְגֻלָּה (sÿgullah, “special property”) is a technical term referring to all the recipients of God’s redemptive grace, especially Israel (Exod 19:5; Deut 7:6; 14:2; 26:18). The Lord says here that he will not forget even one individual in the day of judgment and reward.
