Daniel 10:1-3

In the third year of King Cyrus of Persia, a message was revealed to Daniel, who was named Belteshazzar. The message was true and was about a great conflict. He understood the message and had understanding of the vision. In those days I, Daniel, was mourning for three full weeks. I didn’t eat any rich food, no meat or wine entered my mouth, and I didn’t put any oil on my body until the three weeks were over.
