Kad Yasvun Yisroel

Kad yasvun yisroel vaskin besimchas haTorah, kudsha barich hu omer lefalmaya dilay, chazu banai chavivai, demishtachin betzarah dilhon ve'askin bechedvasah dilay.

When the Jewish people sit, and busy themselves with the joys of Torah, the Holy One Blessed be He, says to all his heavenly hosts: 'Look at at my beloved children as they forget their own sufferings and become immersed in my delight.'
