The Song of the Three Holy Children, also called the Prayer of Azariah, is a lengthy passage that appears after Daniel 3:23 in Roman Catholic and Eastern Orthodox Bibles, as well as in the ancient Greek Septuagint translation.  The passage is omitted from some Protestant Bibles as an apocryphal addition.  The passage includes three main components. The first is the penitential prayer of Daniel’s friend Azariah (called Abednego in Babylonian, according to Daniel 1:6–7) while the three youths were in the fiery furnace. The second component is a brief account of a radiant figure who met them in the furnace yet who was unburned. This is said to be an angel, or interpreted by Christians as a prefigurement or theophany of Jesus Christ, in the same vein as Melchisedek. The third component is the hymn of praise they sang when they realized their deliverance.
