3:28-30 What God did for these his servants, would help to keep the Jews to their religion while in captivity, and to cure them of idolatry. The miracle brought deep convictions on Nebuchadnezzar.

changed the king's word—have made the king's attempt to coerce into obedience vain. Have set aside his word (so "alter … word," Ezr 6:11) from regard to God. Nebuchadnezzar now admits that God's law should be obeyed, rather than his (Ac 5:29).

not serve—by sacrificing.
nor worship—by prostration of the body. Decision for God at last gains the respect even of the worldly (Pr 16:7).
