Daniel 1:8-10

However, Daniel determined in his heart not to contaminate himself with the food and wine from the royal table, so he begged the chief official to exempt him from the royal diet. Then God moved on the heart of the chief official to show Daniel favor and compassion. But he warned Daniel, “My lord the king has ordered your meat and drink, and I fear that he will notice if your face starts looking worse than the other men your age. You could put my life in jeopardy with the king.”
