Daniel 3:12

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

There are certain Jews whom thou hast set over the affairs of the province of Babylon - implying that the high honours conferred on them by the king greatly aggravated by ingratitude the crime of their disobedience.

They serve not thy gods - not only not the golden image, but also not any of Nebuchadnezzar's gods.
