The lyrics, popularized by singer Yisrael Prins and later re-recorded by Avraham Fried, declare: "The Third Temple is not built from stones --- it is built from tears." The educators wanted to know: Does this poetic claim have roots in classical rabbinic literature, specifically in the midrash (the ancient Jewish interpretive texts)? No midrash contains such a statement, he said, suggesting the idea may have been invented by someone in later generations. Indeed, a search through classical rabbinic sources yields no such quotation. However, the concept does appear in later mystical writings, offering a window into how kabbalistic ideas sometimes enter popular Jewish consciousness through music and poetry.
