'Serve' in the Bible

There are certain Jews whom thou hast appointed over the affairs of the province of Babylon: Shadrach, Meshach, and Abed-nego; these men, O king, have not regarded thee: they serve not thy gods, nor worship the golden image which thou hast set up.

Nebuchadnezzar answered and said unto them, Is it of purpose, O Shadrach, Meshach, and Abed-nego, that ye serve not my god, nor worship the golden image which I have set up?

If it be'so , our God whom we serve is able to deliver us from the burning fiery furnace; and he will deliver us out of thy hand, O king.

But if not, be it known unto thee, O king, that we will not serve thy gods, nor worship the golden image which thou hast set up.

Nebuchadnezzar spake and said, Blessed be the God of Shadrach, Meshach, and Abed-nego, who hath sent his angel, and delivered his servants that trusted in him, and have changed the king's word, and have yielded their bodies, that they might not serve nor worship any god, except their own God.

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.

And the kingdom and the dominion, and the greatness of the kingdoms under the whole heaven, shall be given to the people of the saints of the Most High: his kingdom is an everlasting kingdom, and all dominions shall serve and obey him.
