Daniel 10:1-3

In the third year of the reign of King Cyrus of Persia, Daniel (also known as Belteshazzar) had another vision. He understood that the vision concerned events certain to happen in the future—times of war and great hardship. When this vision came to me, I, Daniel, had been in mourning for three whole weeks. All that time I had eaten no rich food. No meat or wine crossed my lips, and I used no fragrant lotions until those three weeks had passed.
