Ezekiel 26:3-4

Therefore thus saith the Lord GOD; Behold, I am against thee, O Tyrus, and will cause many nations to come up against thee, as the sea causeth his waves to come up.

I ... will cause many nations to come up against thee, as the sea causeth his waves to come up. In striking contrast to the boasting of Tyre, God threatens to bring against her Babylon's army, levied from "many nations," even as the Mediterranean waves that dashed against her rock-founded city on all sides.

I will also scrape her dust from her, and make her like the top of a rock - or 'a bare rock' (Grotius). The soil which the Tyrians had brought together upon the rock on which they built their city I will scrape so clean away as to leave no dust, but only the bare rock as it was. An awful contrast to her expectation of filling herself with all the wealth of the East, now that Jerusalem has fallen.
