Charles Ellicott Commentary Zephaniah 3:15

"Jehovah hath taken away thy judgments, he hath cast out thine enemy: the King of Israel, even Jehovah, is in the midst of thee; thou shalt not fear evil any more." — Zephaniah 3:15 (ASV)

Taken away your judgments. — that is, removed what He had “appointed concerning them” (Zephaniah 3:7) in the way of punishments.

The king of Israel. — The recognition of Jehovah as king is elsewhere a prominent feature in the portraiture of the extended dispensation. Thus we have, Say among the heathen that Jehovah is king (Psalms 96:10). Jehovah is king (Psalms 93:1; Psalms 97:1; Psalms 99:1). The kingdom shall be Jehovah’s (Obadiah 1:21).
