Daniel 3:23

Verse 23. And these three men - fell down bound] There is a most evident want of connexion between this and the following verse; and it is between these verses that the apocryphal Song of the Three Children, as it is called, has been inserted by St. Jerome and others; but with this note: Quae sequuntur in Hebraeis voluminibus non reperi; "What follows I have not found in the Hebrew books." And then begins, "They walked in the midst of the flame, praising God, and blessing the Lord." The Septuagint and Arabic read the twenty-fourth verse thus: "Then Nebuchadnezzar heard them singing praise, and was astonished." To connect the two verses Houbigant adds two verses found in the Vulgate, which are the forty-ninth and the twenty-third: "But an angel of the Lord went down with Azariah and his companions into the furnace, and drove out the flame of fire from the furnace; and they walked in the midst of the furnace." This verse (the forty-ninth) has been added to show the reason of Nebuchadnezzar's astonishment, and also to account for the appearance of a fourth person in the furnace, as in Daniel 3:25.
