Daniel 1:10

7 and the ruler of the eunuchs gave them names,—yea 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 laid it upon his heart, that he would not defile himself with the delicacies of the king, nor with the wine which he drank,—therefore sought he of the ruler of the eunuchs, that he might not defile himself.

9 But, although God had brought Daniel into lovingkindness and tender compassion, before the ruler of the eunuchs,

10 yet said the ruler of the eunuchs unto Daniel, I do fear my lord the king, who hath appointed your food and your drink,—for why should he see your faces more sad than those of the youths of your own age? so should ye bring me under the penalty of mine own head unto the king.

11 Then said Daniel, unto the overseer whom the ruler of the eunuchs had appointed over Daniel, Hananiah, Mishael, and Azariah:

12 I pray thee—prove thy servants, ten days,—and let them give us vegetable food, that we may eat, and water that we may drink:

13 then let our countenances be looked upon before thee, and the countenances of the youths who have been eating the delicacies of the king,—and, as thou shalt see, deal thou with thy servants.
