Nahum adds to his prophecy about Judah's freedom from bondage (Nahum 1:13) by predicting a messenger will bring news of peace (see also Isaiah 52:7). The peace message was that Assyria's control over Judah would end, freeing God's people from its burden. This happened during King Josiah's reign from 640 to 609 BC, after Assyrian King Ashurbanipal died in 626 BC.
This political message hints at God's final victory over evil. It foretells the release from sin through the Messiah's saving work, granting eternal peace (Zephaniah 3:13; Luke 2:10–14; Acts 10:34–43; Romans 10:15; Ephesians 2:14–18).
