What is the meaning of Zephaniah 2:15?

* The two F.O.G. Bibles & Commentary below are currently a work in progress.

This carefree city that dwells securely, that thinks to herself: “I am it, and there is none besides me,” what a ruin she has become, a resting place for beasts. Everyone who passes by her hisses and shakes his fist.

Berean Standard Bible (BSB)

This is the joyous city that lived carelessly, that said in her heart, “I am, and there is none besides me.” How she has become a desolation, a place for animals to lie down in! Everyone who passes by her will hiss, and shake their fists.

World English Bible (WEB)

This is the rejoicing{H5947} city{H5892} that dwelt{H3427}{(H8802)} carelessly{H983}, that said{H559}{(H8802)} in her heart{H3824}, I am, and there is none beside{H657} me: how is she become a desolation{H8047}, a place for beasts{H2416} to lie down in{H4769}! every one that passeth by{H5674}{(H8802)} her shall hiss{H8319}{(H8799)}, and wag{H5128}{(H8686)} his hand{H3027}.

Strong's King James

This is the jubilant city which dwells securely, Who says in her heart, "Me! There is none besides me!" How she has become a wasteland, a resting place for wild animals! Everyone passing by her will jeer and shake their fist.

The F.O.G Paraphrase

This is the exulting city that is dwelling confidently, That is saying in her heart, ‘I am, and beside me there is none,’ How hath she been for a desolation, A crouching-place for beasts, Every one passing by her doth hiss, He doth shake his hand!
