בַּיּ֣וֹם הַה֗וּא יֵצְא֨וּ מַלְאָכִ֤ים מִלְּפָנַי֙ בַּצִּ֔ים לְהַחֲרִ֖יד אֶת־כּ֣וּשׁ בֶּ֑טַח וְהָיְתָ֨ה חַלְחָלָ֤ה בָהֶם֙ בְּי֣וֹם מִצְרַ֔יִם כִּ֥י הִנֵּ֖ה בָּאָֽה׃ (ס)
In that day shall messengers go forth from before Me in ships To make the confident Ethiopians afraid; And there shall come convulsion upon them in the day of Egypt; For, lo, it cometh.
