Daniel 1:8

4youths 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.

5The 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.

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

7The 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.

8But 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.

9Now God made Daniel find kindness and compassion in the sight of the prince of the eunuchs.

10The 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? Then you would endanger my head with the king.”

11Then Daniel said to the steward whom the prince of the eunuchs had appointed over Daniel, Hananiah, Mishael, and Azariah:

12“Test your servants, I beg you, ten days; and let them give us vegetables to eat and water to drink.
