וָאֶזְרֵ֥ם בְּמִזְרֶ֖ה בְּשַׁעֲרֵ֣י הָאָ֑רֶץ שִׁכַּ֤לְתִּי אִבַּ֙דְתִּי֙ אֶת־עַמִּ֔י מִדַּרְכֵיהֶ֖ם לוֹא־שָֽׁבוּ׃
And I fan them with a fan in the gates of the land; I bereave them of children, I destroy My people, Since they return not from their ways.
Rashi on Jeremiah
with a sieve A sieve called (van in French), like one who winnows barley, so that they should not all be exiled to one place.
