'Fast' in the Bible

by asking the priests who were at the house of the Lord of Hosts as well as the prophets, “Should we mourn and fast in the fifth month as we have done these many years?”

“Ask all the people of the land and the priests: When you fasted and lamented in the fifth and in the seventh months for these 70 years, did you really fast for Me?

“The Lord of Hosts says this: The fast of the fourth month, the fast of the fifth, the fast of the seventh, and the fast of the tenth will become times of joy, gladness, and cheerful festivals for the house of Judah. Therefore, love truth and peace.”
