Charles Ellicott Commentary Zephaniah 1:6

"and them that are turned back from following Jehovah; and those that have not sought Jehovah, nor inquired after him." — Zephaniah 1:6 (ASV)

Schmieder observes that the enumeration of Zephaniah 1:4-6 extends from gross external to refined internal apostasy. “The Lord will destroy:

1. the idols of Baal;
2. their priests;
3. those who openly worship them on housetops;
4. the secret worshippers;
5. those who, without worshipping idols, have apostatized in their hearts;
6. those who are indifferent to religion.”
