הֶ֣בֶל הֵ֔מָּה מַעֲשֵׂ֖ה תַּעְתֻּעִ֑ים בְּעֵ֥ת פְּקֻדָּתָ֖ם יֹאבֵֽדוּ׃
They are vanity, a work of delusion; In the time of their visitation they shall perish.
Rashi on Jeremiah
at the time of their visitation When I will visit retribution upon them.

They are vanity, a work of delusion; In the time of their visitation they shall perish.
