בַּיּ֣וֹם הַה֗וּא יָגֵ֤ן יְהוָה֙ בְּעַד֙ יוֹשֵׁ֣ב יְרוּשָׁלִַ֔ם וְהָיָ֞ה הַנִּכְשָׁ֥ל בָּהֶ֛ם בַּיּ֥וֹם הַה֖וּא כְּדָוִ֑יד וּבֵ֤ית דָּוִיד֙ כֵּֽאלֹהִ֔ים כְּמַלְאַ֥ךְ יְהוָ֖ה לִפְנֵיהֶֽם׃
In that day shall the LORD defend the inhabitants of Jerusalem; And he that stumbleth among them at that day shall be as David; And the house of David shall be as a godlike being, As the angel of the LORD before them.
