Daniel 10:1-3

In the third year of Cyrus the king of the Persians, a word was revealed to Daniel, who was called by his name Belteshazzar, and the word was reliable and it concerned a great tribulation, and he understood the word and he received understanding. In those days, I, Daniel, I myself was in mourning for three whole weeks. I had not eaten any choice food, and meat and wine did not enter my mouth, and I did not use any ointment until the end of three whole weeks.
