גַּם־בִּשְׂח֥וֹק יִכְאַב־לֵ֑ב וְאַחֲרִיתָ֖הּ שִׂמְחָ֣ה תוּגָֽה׃
웃을 때에도 마음에 슬픔이 있고 즐거움의 끝에도 근심이 있느니라
Rashi
Even with laughter that the Holy One, blessed be He, laughs with the heathens in this world. Their heart will ache in the future, and so Scripture says (Isa. 65:14): “And you shall cry out from sorrow of heart.”
