Daniel 1:7

4 youths in whom was no blemish, but well-favored, and skillful in all wisdom, and endowed with knowledge, and understanding science, and such as had ability to stand in the king's palace; and that he should teach them the learning and the language of the Chaldeans.

5 The king appointed for them a daily portion of the king's royal food, and of the wine which he drank, and that they should be nourished three years; that at its end they should stand before the king.

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

7 The prince of the eunuchs gave names to them: to Daniel he gave the name of Belteshazzar; and to Hananiah, of Shadrach; and to Mishael, of Meshach; and to Azariah, of Abednego.

8 But Daniel determined in his heart that he would not defile himself with the king's royal 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 gave Daniel favor and compassion in the sight of the prince of the eunuchs.

10 The prince of the eunuchs said to Daniel, "I fear my lord the king, who has appointed your food and your drink: for why should he see your faces worse looking than the youths who are of your own age? So would you endanger my head with the king."
