Charles Ellicott Commentary Daniel 4:36

"At the same time mine understanding returned unto me; and for the glory of my kingdom, my majesty and brightness returned unto me; and my counsellors and my lords sought unto me; and I was established in my kingdom, and excellent greatness was added unto me." — Daniel 4:36 (ASV)

For the glory: He means that the splendour returned, so as to increase the honour and glory of his reign.
