Daniel 1:8; Daniel 10:12

8 But Daniel purposed in his heart that he would not defile himself with the portion of the king's meat, nor with the wine which he drank: therefore he requested of the prince of the eunuchs that he might not defile himself.
12 Then said he unto me, Fear not, Daniel: for from the first day that thou didst set thine heart to understand , and to chasten thyself before thy God, thy words were heard , and I am come for thy words.
