The text claims authorship by Zephaniah during the reign of King Josiah of Judah. Josiah ruled from 640 to 609 b.c. Historical analysis places the composition of the core text before Josiah initiated his religious overhaul in 622 b.c. The writer identifies as the great-great-grandson of Hezekiah. This specific lineage serves to legitimize the author among the Jerusalem elite. The manuscript belongs to the prophetic genre and delivers a sustained critique of religious syncretism in the capital. The text targets the localized worship of Baal alongside Yahweh. The author warns of an impending military disaster and frames this event as the Day of the Lord.
The geopolitical landscape of the seventh century b.c. drives the narrative. The Assyrian empire controlled the region but faced internal collapse. The text anticipates the destruction of Nineveh, the Assyrian capital located roughly 500 miles northeast of Jerusalem. Babylonian and Median armies destroyed Nineveh in 612 b.c. The inclusion of this event anchors the material in real historical time. Later editors modified the text after the Babylonian exile to reflect retrospective realities. Zephaniah also targets neighboring states, including Philistia, Moab, Ammon, and Cush, reflecting standard Near Eastern political rivalries.
The writer details the topography of Jerusalem to ground the judgment oracles. The text names specific districts such as the Maktesh, a commercial basin within the city walls where foreign traders operated. It describes the physical hoarding of wealth and the corruption of local officials, judges, and priests. The author uses these concrete urban details to build a case against the leadership class. The manuscript strips away any protection Judah claims from Yahweh, insisting he brings violence against his own people. The text treats the deity as an active military agent who orchestrates the slaughter.
The final section shifts tone and promises survival for a humble remnant. Form critics identify these closing verses as additions that later scribes inserted during the post-exilic period. Scribes added these passages after the Persians allowed Judean elites to return to Jerusalem in 538 b.c. The editors needed to provide hope to the returning population. They appended a vision of restored fortunes to an otherwise bleak document of destruction.
