Daniel 1:6-8

Among these were Daniel, Hananiah, Mishael, and Azariah of the tribe of Judah. And the chief of the eunuchs gave them names: Daniel he called Belteshazzar, Hananiah he called Shadrach, Mishael he called Meshach, and Azariah he called Abednego. But Daniel resolved that he would not defile himself with the king’s food, or with the wine that he drank. Therefore he asked the chief of the eunuchs to allow him not to defile himself.
