Al sh'loshah d'varim (haolam omeid)
Al hatorah, v'al ha'avodah, v'al g'milut chasadim
עַל שְׁלֹשָׁה דְּבָרִים (הָעוֹלָם עוֹמֶד:)
עַל הַתּוֹרָה, וְעַל הַעֲבוֹדָה וְעַל גְּמִילוּת
The Words in Parentheses are not sung, but are part of the original text
Upon three things (the world is standing)
On Torah, on the service [of prayer], and on giving grace/kindness
The words are taken from a short statement of Pirkei Avot (lit. Chapters of the Fathers), a compilation of ethical teachings reaching back to Sinai.
The song, which emphasizes the importance of Torah, is most often heard today in Reform temples during the part of the service before the Torah is read. However, the songs fits just as well as a short zemer for a kumzitz or Seudah Shelishit.
