Daniel 4:37

Now I, Nebuchadnezzar, in issuing this decree with its frank confession, praise and extol and honor the King of heaven, the heaping of synonyms showing the intensity of the king's convictions, all whose works are truth, and His ways judgment, so that Nebuchadnezzar freely acknowledged his punishment to have been well deserved; and those that walk in pride, exalting themselves at the expense of God's honor, He is able to abase. While Nebuchadnezzar recognized the humiliation which he had suffered as a just punishment of his pride, yet he did not realize the greatness of God's grace and mercy which was striving to gain him for true repentance. It is safe to assume, however, that this experience was a step in the right direction, and that this great heathen king finally died in the true faith.
