'Blessed Be the God' in the Bible

Then spake Nebuchadnezzar, and said, "Blessed be the God of Shadrach, Meshach, and Abednego: which hath sent his angel, and defended his servants that put their trust in him: that have altered the king's commandment, and jeopardized their bodies thereupon, rather than they would serve or worship any other god except their own God only.
