Nahum’s singular focus on the impending judgment of Nineveh offers a continuation of the story that began in Jonah. Sometime around 760 BC, God sent Jonah to Nineveh to preach repentance and hope to the Assyrian people, a message they heard and adopted—at least for a time. One hundred years later, during the time of Nahum, the Assyrians had returned to their bullish ways, conquering the northern kingdom of Israel and lording their power over Judah in the south (2 Kings 17:1–6; 18:13–19:37). Jonah failed to realize what Nahum reminded the people of Judah: God’s justice is always right and always sure. Should He choose to grant mercy for a time, that good gift will not compromise the Lord’s ultimate sense of justice for all in the end.     (Chuck Swindoll)
