'Serve' in the Bible

Nebuchadnezzar hath answered and hath said, 'Blessed is the God of Shadrach, Meshach, and Abed-Nego, who hath sent His messenger, and hath delivered His servants who trusted on Him, and the word of the king changed, and gave up their bodies that they might not serve nor do obeisance to any god except to their own God.

A flood of fire is proceeding and coming forth from before Him, a thousand thousands do serve Him, and a myriad of myriads before Him do rise up, the Judge is seated, and the books have been opened.

And to him is given dominion, and glory, and a kingdom, and all peoples, nations, and languages do serve him, his dominion is a dominion age-during, that passeth not away, and his kingdom that which is not destroyed.

and the kingdom, and the dominion, even the greatness of the kingdom under the whole heavens, is given to the people -- the saints of the Most High, His kingdom is a kingdom age-during, and all dominions do serve and obey Him.
