And thus is it written (Song of Songs 7:5) "Your eyes are like the pools in Cheshbon by the gate of Bath-rabbim": "Your eyes": These are the elders appointed over the congregation, viz. (Isaiah 29:10) "For the L-rd has poured upon you a spirit of deep sleep, and He has closed your 'eyes' from seeing." "pools": Just as one cannot plumb (the depths of) a pool, so he cannot plumb the words of the sages. "in Cheshbon": the "accountings" (cheshbonoth) that they conclude with counsel and deliberation (machshavah).
These are concluded in the houses of study, by "the gate (of study) frequented by the many (scholars)" — bath-rabbim. What is the intent of (Song of Songs, Ibid.) "Your nose is like the tower of Levanon which looks towards Damascus"? If you have studied the Torah, hope for (i.e., anticipate the arrival of) Eliyahu, whom I told (I Kings 19:15) "Go, return on your way, to the desert of Damascus."
And it is written (Malachi 3:22-24) "Remember the Torah of Moses, My servant, which I commanded you in Chorev for all of Israel, statues and judgments. Behold, I am sending you Eliyahu the prophet before the coming of the day of the L-rd, and he will turn back (to the L-rd) the hearts of fathers with (their) sons, and the heart of sons with their fathers" — this being the purport of "which I command you this day."
