The Jewish community fluctuated between 8–10 families throughout the 16th century, and suffered from severe financial straits in the first half of the century. In 1540, renowned kabbalist Malkiel Ashkenazi bought a courtyard from the small Karaite community, in which he established the Sephardic Abraham Avinu Synagogue. In 1659, Abraham Pereyra of Amsterdam founded the "Hesed Le'Abraham yeshiva" in Hebron, which attracted many students. In the early 18th century, the Jewish community suffered from heavy debts, almost quadrupling from 1717–1729, and were "almost crushed" from the extortion practiced by the Turkish pashas. In 1773 or 1775, a substantial amount of money was extorted from the Jewish community, who paid up to avert a threatened catastrophe, after a false allegation was made accusing them of having murdered the son of a local sheikh and throwing his body into a cesspit.> Emissaries from the community were frequently sent overseas to solicit funds.
