Daniel 1:8-10

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

9Now God had brought Daniel into the favor and goodwill of the chief of the eunuchs.

10And the chief of the eunuchs said to Daniel, “I fear my lord the king, who has appointed your food and drink. For why should he see your faces looking worse than the young men who are your age? Then you would endanger my head before the king.”
