I've heard it symbolically preached that these verses are advised this day, to serve the State.
"And now have I given all these lands into the hand of Nebuchadnezzar the king of Babylon, my servant; and the beasts of the field have I given him also to serve him. And all nations shall serve him, and his son, and his son's son, until the very time of his land come: and then many nations and great kings shall serve themselves of him. And it shall come to pass, that the nation and kingdom which will not serve the same Nebuchadnezzar the king of Babylon, and that will not put their neck under the yoke of the king of Babylon, that nation will I punish, saith the LORD, with the sword, and with the famine, and with the pestilence, until I have consumed them by his hand."-Jeremiah 27:6-8, 11 KJV
"But the nations that bring their neck under the yoke of the king of Babylon, and serve him, those will I let remain still in their own land, saith the LORD; and they shall till it, and dwell therein."
Though these verses were for those specific prophesied times, yet it wasn't that they were spiritually serving them. For Daniel himself asked for pulse and water instead of the king's meat and wine.
Neither would Daniel observe the law of prayer.
"All the presidents of the kingdom, the governors, and the princes, the counsellers, and the captains, have consulted together to establish a royal statute, and to make a firm decree, that whosoever shall ask a petition of any God or man for thirty days, save of thee, O king, he shall be cast into the den of lions."-Daniel 6:7 KJV
"Now when Daniel knew that the writing was signed, he went into his house; and his windows being open in his chamber toward Jerusalem, he kneeled upon his knees three times a day, and prayed, and gave thanks before his God, as he did aforetime."-Daniel 6:10 KJV
Nor Hananiah, Mishael, nor Azariah bowed down and worship the golden image. But their necks not souls were under the yoke to pay taxes, and work the lands. As in the upcoming Roman invasion would also dominate and require fleshly observance.
