Complete Commentary on the Whole Bible, by Matthew Henry, at sacred-texts.com
(Mic 3:1-8) The cruelty of the princes, and the falsehood of the prophets.
(Mic 3:9-12) Their false security.
Men cannot expect to do ill, and fare well; but to find that done to them which they did to others. How seldom do wholesome truths reach the ears of those in high stations or in authority! Those who deceive others are preparing confusion for their own faces. The prophet had ardent love to God and to the souls of men; deep concern for his glory and their salvation, and zeal against sin. The difficulties he met with did not drive him from his work. He had this strength; not from and of himself, but he was full of power by the Spirit of the Lord. Those who act honestly, may act boldly. And those who come to hear the word of God, must be willing to be told of their faults, must take it kindly, and be thankful.
Zion's walls owe no thanks to those that build them up with blood and iniquity. The sin of man works not the righteousness of God. Even when men do that which in itself is good, but do it for filthy lucre, it becomes abomination both to God and man. Faith rests in the Lord as the soul's foundation: presumption only leans upon the Lord as a prop, and would use him to serve a turn. If men's having the Lord among them will not keep them from doing evil, it never can secure them from suffering evil for so doing. See the doom of wicked Jacob; Therefore shall Zion for your sake be ploughed as a field. This was exactly fulfilled at the destruction of Jerusalem by the Romans, and is so at this day. If sacred places are polluted by sin, they will be wasted and ruined by the judgments of God.
