בַּיּ֣וֹם הַה֔וּא יִֽהְיֶ֥ה מִצְרַ֖יִם כַּנָּשִׁ֑ים וְחָרַ֣ד ׀ וּפָחַ֗ד מִפְּנֵי֙ תְּנוּפַת֙ יַד־יְהוָ֣ה צְבָא֔וֹת אֲשֶׁר־ה֖וּא מֵנִ֥יף עָלָֽיו׃
In that day shall Egypt be like unto women; and it shall tremble and fear because of the shaking of the hand of the LORD of hosts, which He shaketh over it.
