Adam Clarke on Malachi 3:5

I will come near to you to judgment - And what fearful cases does he get to judge! Sorcerers, adulterers, false swearers, defrauders of the wages of the hireling, oppressors of widows and orphans, and perverters of the stranger and such as do not fear the Lord: a horrible crew; and the land at that time was full of them. Several were converted under the preaching of Christ and his apostles, and the rest the Romans destroyed or carried into captivity.
