Daniel 10:1-3

In the third year of Cyrus king of Persia, I, Daniel, known as Belteshazzar, received a profound word—a true revelation, but I struggled to understand it. Finally, its interpretation was disclosed to me in a vision, and I began to understand the word. At that time, I was in a period of mourning for three weeks. During the entire three weeks, I ate no delicacies —no meat and no sweets. I drank no wine, nor did I groom myself.
