Daniel 1:7-8

Ashpenaz, the chief officer, gave them Babylonian names. Daniel’s new name was Belteshazzar, Hananiah’s was Shadrach, Mishael’s was Meshach, and Azariah’s was Abednego. Daniel decided not to eat the king’s food or drink his wine because that would make him unclean. So he asked Ashpenaz for permission not to make himself unclean in this way.
