(where Yaakov blesses Yehudah)
"His eyes sparkle more than wine ..."
The 4th Lubavitcher Rebbe (the Maharash), in discussing this Targum (Torat Shmuel 1872, p.142), curiously, "misquotes" the Targum by dropping one word and changing the spelling of the next word, to read,
Slight as the change is, for the meaning rendered remains the same, no such change occurs for nothing, most especially by a Rebbe of Chabad - who is always meticulously precise! So a Lubavitcher chassid (heard from S.B. Zuta) took pencil to paper to doodle with the numbers. Amazingly, the modified version of the verse from Targum - as quoted by the Maharash - in Gematria - yields 770! It's as if the Maharash already back then had seen into the eyes of Moshiach and could not help himself from changing the words slightly, to offer an impulsive albeit cloaked prophecy, thereby implicating 770 as the future House of Moshiach (בית משיח = 770).
Some will of course say it's a coincidence. But there are no coincidences in the universe - especially for a Rebbe, the Moses of his generation!
