Daniel 1:8-10

But Daniel purposed in his heart that he would not defile himself with the king’s dainties, nor with the wine which he drank: therefore he requested of the prince of the eunuchs that he might not defile himself. Now God made Daniel to find kindness and compassion in the sight of the prince of the eunuchs. And the prince of the eunuchs said unto Daniel, I fear my lord the king, who hath appointed your food and your drink: for why should he see your faces worse looking than the youths that are of your own age? so would ye endanger my head with the king.
