Daniel 10:1-3 NKJV
In 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. In those days I, Daniel, was mourning three full weeks. I 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.
