Daniel 10:1-3

1In 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.

2In those days I, Daniel, was mourning for three weeks.

3I ate no delicacies, no meat or wine entered my mouth, nor did I anoint myself at all, for the full three weeks.
