Daniel 1:8-10

8 And Daniel had come to the decision that he would not make himself unclean with the king's food or wine; so he made a request to the captain of the unsexed servants that he might not make himself unclean.

9 And God put into the heart of the captain of the unsexed servants kind feelings and pity for Daniel.

10 And the captain of the unsexed servants said to Daniel, I am in fear of my lord the king, who has given orders about your food and your drink; what if he sees you looking less happy than the other young men of your generation? then you would have put my head in danger from the king.
