In 1684, a group of Spanish and Portuguese Jews who fled the Inquisition (see "Today in Jewish History" for Tevet 22) held a Rosh Hashanah service in New Amsterdam, thereby founding congregation Shearith Israel ("Remnant of Israel"). On this 17th of Tevet in 1728, the congregation purchased a lot in Lower Manhattan to erect the first synagogue in New York.
Rabbi Aaron Zelig ben Joel Feivush of Ostrog, Russia, author of Toldot Aaron, passed away on Tevet 17 of the year in 5515 from creation (1754).
Tevet 17 is also the yahrtzeit of Rabbi Yaakov Wolf Krantz (1740-1804), the Maggid (preacher) of Dubna, particularly known for the parables (meshalim) he employed in his sermons and writings.
“The man Moses was more humble than any human being on the face of the earth.” (Numbers 12:3)
Moses didn’t fool himself. He knew how good he was. He knew he stood on a level beyond any other human being. Yet he was humbled before them.
Because he knew that all that he had achieved was only with the capabilities given to him from Above. He figured that if someone else were given these same capabilities, that person would achieve as much as him.
And who knows, perhaps someone else would have used those capabilities to their fullest and achieved even more.
