Jeremiah

And Jehoshaphat feared, and set himself to seek the Lord, and proclaimed a fast throughout all Judah.

Therefore go thou, and read in the roll, which thou hast written from my mouth, the words of the Lord in the ears of the people in the Lord’s house upon the fasting day: and also thou shalt read them in the ears of all Judah that come out of their cities.

Go, gather together all the Jews that are present in Shushan, and fast ye for me, and neither eat nor drink three days, night or day: I also and my maidens will fast likewise; and so will I go in unto the king, which is not according to the law: and if I perish, I perish.

So the people of Nineveh believed God, and proclaimed a fast, and put on sackcloth, from the greatest of them even to the least of them.

Now the king sat in the winterhouse in the ninth month: and there was a fire on the hearth burning before him.
