18 You have seen the greatness of his evil deeds: come now to God's loving-kindness. He was turned into a wild beast, he abode in the wilderness, he was scourged, that he might be saved. He had claws as a lion; for he was a ravager of the Sanctuary. He had a lion's mane: for he was a ravening and a roaring lion. He ate grass like an ox: for a brute beast he was, not knowing Him who had given him the kingdom. His body was wet from the dew; because after seeing the fire quenched by the dew he believed not. And what happened? After this, says he, I, Nabuchodonosor, lifted up my eyes unto heaven, and I blessed the Most High, and to Him that lives for ever I gave praise and glory. When, therefore, he recognised the Most High, and sent up these words of thankfulness to God, and repented himself for what he had done, and recognised his own weakness, then God gave back to him the honour of the kingdom.
