'Rich' in the Bible

Daniel determined within himself not to become defiled by the king's menu of rich foods or by the king's wine, so he requested permission from the chief officer not to defile himself.

Then compare how we look with the young men who ate the king's rich food, and treat your servants in accordance with what you observe."

At the end of ten days their appearance was better and their faces were well-nourished compared to the young men who ate the king's rich food.

So the guard took away their rich food and wine, giving them vegetables.
