Daniel 10:1-3

In the third year of Cyrus king of Persia a message was revealed to Daniel, who was named Belteshazzar; and the message was true and it referred to great conflict (warfare, misery). And he understood the message and had an understanding of the vision. [Dan 8:26; Rev 19:9] In those days I, Daniel, had been mourning for three entire weeks. I ate no tasty food, nor did any meat or wine enter my mouth; and I did not anoint (refresh, groom) myself at all for the full three weeks.
