Daniel 1:5-8

5The king assigned them daily provisions from the royal food and from the wine that he drank. They were to be trained for three years, and at the end of that time they were to attend the king.

6Among them, from the Judahites, were Daniel, Hananiah, Mishael, and Azariah.

7The chief eunuch gave them names; he gave the name Belteshazzar to Daniel, Shadrach to Hananiah, Meshach to Mishael, and Abednego to Azariah.

8Daniel determined that he would not defile himself with the king’s food or with the wine he drank. So he asked permission from the chief eunuch not to defile himself.
