וְהָיְתָ֣ה הַחֶ֗רֶב אֲשֶׁ֤ר אַתֶּם֙ יְרֵאִ֣ים מִמֶּ֔נָּה שָׁ֛ם תַּשִּׂ֥יג אֶתְכֶ֖ם בְּאֶ֣רֶץ מִצְרָ֑יִם וְהָרָעָ֞ב אֲשֶׁר־אַתֶּ֣ם ׀ דֹּאֲגִ֣ים מִמֶּ֗נּוּ שָׁ֣ם יִדְבַּ֧ק אַחֲרֵיכֶ֛ם מִצְרַ֖יִם וְשָׁ֥ם תָּמֻֽתוּ׃
너희의 두려워하는 칼이 애굽 땅으로 따라가서 너희에게 미칠 것이요 너희의 두려워하는 기근이 애굽으로 급히 따라가서 너희에게 임하리니 너희가 거기서 죽을 것이라
Rashi
and a third you shall scatter to the wind symbolizing the exiles who will go to Egypt, viz. Johanan son of Kareach and his associates, and there I shall unsheathe a sword [in pursuit] after them, for Nebuchadnezzar went and destroyed Egypt, and there they were slain.
Sforno
והריקותי אחריכם חרב, a reference to Nevuchadnezzar’s sword, the latter invading Egypt as predicted by Jeremiah in Jeremiah 42,15.
