Daniel 1:6

4 youths in whom was no defect, but well-favored, skillful in all wisdom, endowed with knowledge, understanding science, and who had the 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 delicacies 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 of the children of Judah were Daniel, Hananiah, Mishael, and Azariah.

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

8 But Daniel purposed in his heart that he would not defile himself with the king’s delicacies, nor with the wine which he drank. Therefore he requested of the prince of the eunuchs that he might not defile himself.
