Daniel 10:1-3

In the third year of Cyrus king of Persia a word was revealed to Daniel, who was named Belteshazzar. And the word was true, and it was a great conflict. And he understood the word and had understanding of the vision. In those days I, Daniel, was mourning for three weeks. I ate no delicacies, no meat or wine entered my mouth, nor did I anoint myself at all, for the full three weeks.
