וְעוֹרֵ֨ר עָלָ֜יו יְהוָ֤ה צְבָאוֹת֙ שׁ֔וֹט כְּמַכַּ֥ת מִדְיָ֖ן בְּצ֣וּר עוֹרֵ֑ב וּמַטֵּ֙הוּ֙ עַל־הַיָּ֔ם וּנְשָׂא֖וֹ בְּדֶ֥רֶךְ מִצְרָֽיִם׃
And the LORD of hosts shall stir up against him a scourge, as in the slaughter of Midian at the Rock of Oreb; and as His rod was over the sea, so shall He lift it up after the manner of Egypt.
Ibn Ezra on Isaiah
וכמכת מטהו═ומטהו. As he smote with his staff at the sea, when the water flowed back over the Egyptians.
