וְהָיָה֙ כִּצְבִ֣י מֻדָּ֔ח וּכְצֹ֖אן וְאֵ֣ין מְקַבֵּ֑ץ אִ֤ישׁ אֶל־עַמּוֹ֙ יִפְנ֔וּ וְאִ֥ישׁ אֶל־אַרְצ֖וֹ יָנֽוּסוּ׃
And it shall come to pass, that as the chased gazelle, And as sheep that no man gathereth, They shall turn every man to his own people, And shall flee every man to his own land.
Rashi on Isaiah
like a roving deer i.e., like a deer roving from its place.
