Daniel 10:1-3

1In the third year of Cyrus king of Persia a message was revealed to Daniel, whose name was called Belteshazzar. The message was true, but the appointed time was long; and he understood the message, and had understanding of the vision.

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

3I ate no pleasant food, no meat or wine came into my mouth, nor did I anoint myself at all, till three whole weeks were fulfilled.
