Daniel 10:1-3

1In the third year of King Cyrus of Persia a message was revealed to Daniel, whose name was called Belteshazzar. The oracle was true and concerns a great war. He understood the message and gained insight through a vision.

2“In those days, I, Daniel was mourning for three whole weeks.

3I ate no rich food, nor did meat or wine enter my mouth, nor did I anoint myself with oil, until the end of three weeks.
