וְהָיָה֙ בַּיּ֣וֹם הַה֔וּא תִּֽהְיֶ֧ה מְהֽוּמַת־יְהוָ֛ה רַבָּ֖ה בָּהֶ֑ם וְהֶחֱזִ֗יקוּ אִ֚ישׁ יַ֣ד רֵעֵ֔הוּ וְעָלְתָ֥ה יָד֖וֹ עַל־יַ֥ד רֵעֵֽהוּ׃
And it shall come to pass in that day, That a great tumult from the LORD shall be among them; And they shall lay hold every one on the hand of his neighbour, And his hand shall rise up against the hand of his neighbour.
