'Fast' in the Bible

If they fast, I will not hear their cry of despair. If they offer burnt offering and grain offering, I will not accept them. Rather, I will finish them off by sword, famine, and plague.”

In the fifth year of Jehoiakim son of Josiah, king of Judah, in the ninth month, all the people of Jerusalem and all those coming in from Judah’s cities into Jerusalem proclaimed a fast before the Lord.

This is what the Lord of Hosts says:Israelites and Judeans alike have been oppressed.All their captors hold them fast;they refuse to release them.
