4:28-37 Pride and self-conceit are sins that beset great men. They are apt to take that glory to themselves which is due to God only. While the proud word was in the king's mouth, the powerful word came from God. His understanding and his memory were gone, and all the powers of the rational soul were broken. How careful we ought to be, not to do any thing which may provoke God to put us out of our senses! God resists the proud. Nebuchadnezzar would be more than a man, but God justly makes him less than a man. We may learn to believe concerning God, that the most high God lives for ever, and that his kingdom is like himself, everlasting, and universal. His power cannot be resisted. When men are brought to honour God, by confession of sin and acknowledging his sovereignty, then, and not till then, they may expect that God will honour them; not only restore them to the dignity they lost by the sin of the first Adam, but add excellent majesty to them, from the righteousness and grace of the Second Adam. Afflictions shall last no longer than till they have done the work for which they were sent. There can be no reasonable doubt that Nebuchadnezzar was a true penitent, and an accepted believer. It is thought that he did not live more than a year after his restoration. Thus the Lord knows how to abase those that walk in pride, but gives grace and consolation to the humble, broken-hearted sinner who calls upon Him.

27. break off—as a galling yoke (Ge 27:40); sin is a heavy load (Mt 11:28). The Septuagint and Vulgate translate not so well, "redeem," which is made an argument for Rome's doctrine of the expiation of sins by meritorious works. Even translate it so, it can only mean; Repent and show the reality of thy repentance by works of justice and charity (compare Lu 11:41); so God will remit thy punishment. The trouble will be longer before it comes, or shorter when it does come. Compare the cases of Hezekiah, Isa 38:1-5; Nineveh, Jon 3:5-10; Jer 18:7, 8. The change is not in God, but in the sinner who repents. As the king who had provoked God's judgments by sin, so he might avert it by a return to righteousness (compare Ps 41:1, 2; Ac 8:22). Probably, like most Oriental despots, Nebuchadnezzar had oppressed the poor by forcing them to labor in his great public works without adequate remuneration.
