John Trapp on Zephaniah 1:6

Verſe 6. And them that are turned back from the Lord] Not groſſe idolaters, but yet treacherous backſliders, that fall off from their former forwardneſſe, that turn from the holy Commandement, 2 Pet. 2.21. that depart à poſt Dominum, from after the Lord, as the Hebrew here hath it, Apoſtates, thoſe worſt of men, that do not onely not fulfill after the Lord, as Calch, but utterly forſake him. An heavie judgement awaiteth ſuch.Pſal. 125.5. God ſhall lead them forth with the workers of iniquity, &c.

and thoſe that have not ſought the Lord, nor enquired after him] diligently ſought him, Heb. 11.6. zealouſly enquired after him, as after a loſt jewel, Jer. 29.13. God will viſit for unzealouſneſſe; and curſe thoſe that do his work careleſly, curſorily, in a perfunctory, formall, bedulling way.
