Nahum
The book of Nahum is God’s judgment against the kingdom of Assyria, specifically the city of Nineveh. God used the Assyrian’s to bring judgment of his people for their rebellion and disobedience. Through Nahum, God also declared that the Assyrian Empire would fall as well.
Even though God allowed Israel’s defeat because of their sin, he would not let this cancel out his promises to them. He would restore them according to his promise if they would repent and return to him.
