Easton's Bible Dictionary (1897)
Aku’s command, the Chaldean name given to Hananiah, one of the Hebrew youths whom Nebuchadnezzar carried captive to Babylon (Dan. 1:6, 7; 3:12-30). He and his two companions refused to bow down before the image which Nebuchadnezzar had set up on the plains of Dura. Their conduct filled the king with the greatest fury, and he commanded them to be cast into the burning fiery furnace. Here, amid the fiery flames, they were miraculously preserved from harm. ” Thus Nebuchadnezzar learned the greatness of the God of Israel.

(royal, or the great scribe) the Hebrew, or rather Chaldee, name of Hananiah. The history of Shadrach or Hananiah, as told in Dani 1-3 is well known. After their deliverance from the furnace, we hear no more of Shadrach, Meshach and Abednego, except in (Hebrews 11:33,34) but there are repeated allusions to them in the later apocryphal books, and the martyrs of the Maccabaean period seem to have been much encouraged by their example.
