I Nebuchadnezzar was at {a} rest in mine house, and flourishing in my palace:

(a) There was no trouble that might cause me to dream, and therefore it came only from God.

Wesley's Notes

flourishing-"green." Image from a tree (Jer 17:8). Prosperous (Job 15:32).

Matthew Henry's Concise Commentary

4:1-18 The beginning and end of this chapter lead us to hope, that Nebuchadnezzar was a monument of the power of Divine grace, and of the riches of Divine mercy. After he was recovered from his madness, he told to distant places, and wrote down for future ages, how God had justly humbled and graciously restored him. When a sinner comes to himself, he will promote the welfare of others, by making known the wondrous mercy of God. Nebuchadnezzar, before he related the Divine judgments upon him for his pride, told the warnings he had in a dream or vision. The meaning was explained to him. The person signified, was to be put down from honour, and to be deprived of the use of his reason seven years. This is surely the sorest of all temporal judgments. Whatever outward affliction God is pleased to lay upon us, we have cause to bear it patiently, and to be thankful that he continues the use of our reason, and the peace of our consciences. Yet if the Lord should see fit by such means to keep a sinner from multiplying crimes, or a believer from dishonouring his name, even the dreadful prevention would be far preferable to the evil conduct. God has determined it, as a righteous Judge, and the angels in heaven applaud. Not that the great God needs the counsel or concurrence of the angels, but it denotes the solemnity of this sentence. The demand is by the word of the holy ones, God's suffering people: when the oppressed cry to God, he will hear. Let us diligently seek blessings which can never be taken from us, and especially beware of pride and forgetfulness of God.
