Daniel 1:6

3 And the king spoke to Ashpenaz the master of his eunuchs, that he should bring [certain] of the children of Israel, and of the king's seed, and of the princes;

4 Children in whom [was] no blemish, but of good appearance, and skillful in all wisdom, and intelligent in knowledge, and understanding science, and such as [had] ability in them to stand in the king's palace, and whom they might teach the learning and the language of the Chaldeans.

5 And the king appointed them a daily provision of the king's food, and of the wine which he drank: so nourishing them three years, that at the end of them they might stand before the king.

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

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

8 But Daniel purposed in his heart that he would not defile himself with the portion of the king's food, nor with the wine which he drank: therefore he requested of the prince of the eunuchs that he might not defile himself.

9 Now God had brought Daniel into favor and tender love with the prince of the eunuchs.
