Daniel 1:3-7 (NIV)
 Then the king ordered Ashpenaz, chief of his court officials, to bring in some of the Israelites from the royal family and the nobility—
 young men without any physical defect, handsome, showing aptitude for every kind of learning, well informed, quick to understand, and qualified to serve in the king’s palace. He was to teach them the language and literature of the Babylonians.
 The king assigned them a daily amount of food and wine from the king’s table. They were to be trained for three years, and after that they were to enter the king’s service.
 Among these were some from Judah: Daniel, Hananiah, Mishael and Azariah.
 The chief official gave them new names: to Daniel, the name Belteshazzar; to Hananiah, Shadrach; to Mishael, Meshach; and to Azariah, Abednego.
So, I was reading through the book of Daniel, when I realized we know Daniel by his Hebrew name, but Hananiah, Mishael and Azariah we know by their Babylonian names, Shadrach, Meshach and Abednego.
I'm normally interested in detail like this for some reason…
