Nebuchadnezzar was the proud king of Babylon who ignored the God of Israel and saw himself as greater than God. But God humbled Nebuchadnezzar:

“He was driven from among men and ate grass like an ox, and his body was wet with the dew of heaven till his hair grew as long as eagles’ feathers, and his nails were like birds’ claws.  At the end of the days I, Nebuchadnezzar, lifted my eyes to heaven, and my reason returned to me, and I blessed the Most High, and praised and honored him who lives forever, for his dominion is an everlasting dominion, and his kingdom endures from generation to generation; all the inhabitants of the earth are accounted as nothing, and he does according to his will among the host of heaven and among the inhabitants of the earth; and none can stay his hand or say to him, ‘What have you done?’”

Nebuchadnezzar no longer saw himself as the source of his greatness, but he saw the God of Israel as the truly great One and the only One worthy of being treasured and receiving praise. Once Nebuchadnezzar was humbled and understood and treasured God for who he truly was, his heart could not help but burst into praise to God the Most High.
