'Fast' in the Bible

Why, then, do these people of Jerusalem continually turn away from me in apostasy? They hold fast to their deception. They refuse to turn back to me.

Even if they fast, I will not hear their cries for help. Even if they offer burnt offerings and grain offerings, I will not accept them. Instead, I will kill them through wars, famines, and plagues."

So you go there the next time all the people of Judah come in from their towns to fast in the Lord's temple. Read out loud where all of them can hear you what I told you the Lord said, which you wrote in the scroll.

All the people living in Jerusalem and all the people who came into Jerusalem from the towns of Judah came to observe a fast before the Lord. The fast took place in the ninth month of the fifth year that Jehoiakim son of Josiah was ruling over Judah.
