אָ֤ז יִמָּלֵ֪א שְׂח֡וֹק פִּינוּ֮ וּלְשׁוֹנֵ֪נוּ רִ֫נָּ֥ה אָ֭ז יֹאמְר֣וּ בַגּוֹיִ֑ם הִגְדִּ֥יל יְ֝הוָ֗ה לַעֲשׂ֥וֹת עִם־אֵֽלֶּה׃
Dann füllte sich unser Mund mit Lachen und unsere Zunge mit Jubel. Dann sprach man unter den Völkern: Der Herr hat Großes an diesen getan.

R. Johanan said in the name of R. Simeon b. Johai : It is forbidden that a man's mouth be filled with laughter in this world ; because it is written, "Then will our mouth be filled with laughter, and our tongue with singing" (Ps. cxxvi. 2). When ? At the time when "They will say among the nations. The Lord hath done great things with these" (ibid.). It was said of R. Simeon b. Lakish that never again was his mouth full of laughter in this world after hearing this teaching from his master R. Johanan.
