A Jealous God

It was approximately 87 years from the time that Nineveh had turned from their sins due to the preaching of Jonah until Nahum's prophecy. Then some 30 years, or so later, Nineveh fell to the allied forces of Nabopolasor, of Babylon, and the Medes.

Even with Nineveh going back to her wicked ways, the Lord still showed His Grace, Mercy, and Loving kindness. Still, the Lord keeps His Word!
