Albert Barnes Commentary Zephaniah 1:3

"I will consume man and beast; I will consume the birds of the heavens, and the fishes of the sea, and the stumblingblocks with the wicked; and I will cut off man from off the face of the ground, saith Jehovah." — Zephaniah 1:3 (ASV)

The stumbling-blocks with the wicked - Not only will the wicked be utterly brought to an end, or, in the other meaning of the word, “gathered into bundles to be taken away,” but all causes of stumbling as well; everything through which others can fall, which will not be until the end of all things. Then, he repeats, yet more emphatically, I will cut off the whole race of man from the face of the earth, and then he closes the verse, like the previous one, with the solemn words, saith the Lord. All this will be fulfilled in the Day of Judgment, and all other fulfillments are pledges of the final Judgment.

They are witnesses of the ever-living presence of the Judge of all, that God does take account of man’s deeds. They speak to men’s conscience, they attest the existence of a divine law, and with it, of the future complete manifestation of that law, of which they are individual sentences. Not until the prophet has brought this circle of judgments to a close does he pass on to the particular judgments on Judah and Jerusalem.
