Yonah 3:4-6

Orthodox Jewish Bible

⁴ And Yonah began to enter into the city one day’s journey, and he cried out and preached, and said, Yet arba’im yamim (40 days), and Nineveh shall be overthrown.

⁵ So the people of Nineveh had emunah in Elohim, and proclaimed a tzom, and put on sackcloth, from their gedolim even to their ketanim.

⁶ For word came unto HaMelech of Nineveh, and he arose from his kisse, and he laid aside his royal robe, and covered him with sackcloth, and sat in ashes.
