Printed in the original as Baruch chapter 6. The chapter number 6 is also shown in the NRSV. However, in the Septuagint, Lamentations comes between Baruch chapter 5 and Letter of Jeremiah.
This makes more sense to me now concerning the 3 Hebrew boys who would not bow down to King Nabuchodonosor, if this at all is the same king. I often wondered how they even knew about Almighty God. Or that he could save them from the fiery furnace, since they were taken into captivity and named after foreign gods (idols). Amazing that's all I'm saying. This comment just sheds a little more light concerning them.
