Daniel 3:9

They spake and said to Nebuchadnezzar
Having got access unto him, and within his hearing, they expressed themselves in the following manner: O king, live for ever;
this they said to show their fidelity and hearty attachment to him, and their regard to his welfare, and the continuance of his life; and the rather to ingratiate themselves into his affections, and gain audience of him; (See Gill on Daniel 2:4).
