25 He answered and said, Lo, I see four men loose, walking in the midst of the fire, and they have no hurt; and the form of the fourth is like the Son of God. kjv

25. He called out and said, "Behold, I see four free men walking in the midst of the fire, and there is no wound upon them, and the form of the fourth one is like [that of] an angel." Tanakh

There are no capital letters in Hebrew. So that reading if read as bar would only be 'son' and not Son. KJV capitalizes this in order to make one believe that it is referring to J'sus, when it is referring to the angels which are also called son' of G_d.
