'Serving' in the Bible

There are certain Jews whom thou hast appointed over the work of the province of Babylon -- Shadrach, Meshach, and Abed-Nego, these men have not made of thee, O king, any regard; thy gods they are not serving, and to the golden image thou hast raised up -- are not making obeisance.'

Nebuchadnezzar hath answered and said to them, 'Is it a laid plan, O Shadrach, Meshach, and Abed-Nego -- my gods ye are not serving, and to the golden image that I have raised up ye are not doing obeisance?

Lo, it is; our God whom we are serving, is able to deliver us from a burning fiery furnace; and from thy hand, O king, He doth deliver.

And lo -- not! be it known to thee, O king, that thy gods we are not serving, and to the golden image thou hast raised up we do no obeisance.'

Then the king hath said, and they have brought Daniel, and have cast him into a den of lions. The king hath answered and said to Daniel, 'Thy God, whom thou art serving continually, Himself doth deliver thee.'

and at his coming near to the den, to Daniel, with a grieved voice, he crieth. The king hath answered and said to Daniel, O Daniel, servant of the living God, thy God, whom thou art serving continually, is He able to deliver thee from the lions?'
