Daniel 1:5-8

5And the king appointed unto them a daily provision of the king's delicate food, and of the wine that he drank, to nourish them three years, that at the end thereof they might stand before the king.

6Now among these were of the children of Judah, Daniel, Hananiah, Mishael, and Azariah.

7And the prince of the eunuchs gave them names: to Daniel he gave [the name] Belteshazzar, and to Hananiah, Shadrach, and to Mishael, Meshach, and to Azariah, Abed-nego.

8And Daniel purposed in his heart that he would not pollute himself with the king's delicate food, nor with the wine which he drank; and he requested of the prince of the eunuchs that he might not have to pollute himself.
