“Shadrach” means royal , or the great scribe
Shadrach: 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.
