Charles Ellicott Commentary Daniel 7:14

"And there was given him dominion, and glory, and a kingdom, that all the peoples, nations, and languages should serve him: his dominion is an everlasting dominion, which shall not pass away, and his kingdom that which shall not be destroyed." — Daniel 7:14 (ASV)

Serve him.— In Biblical Chaldee this word is only used of rendering Divine service or worship. The “Son of man” is therefore here spoken of as God.
