28 Then Nebuchadnezzar said, "Praise to the God of Shadrach, Meshach, and Abednego! He sent his angel to rescue his servants who trusted in him. They defied the king's command and were willing to die rather than serve or worship any god except their own God.
Matthew Henry's Commentary on Daniel 3:28
Commentary on Daniel 3:28-30
(Read Daniel 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. But no abiding change then took place in his conduct. He who preserved these pious Jews in the fiery furnace, is able to uphold us in the hour of temptation, and to keep us from falling into sin.
