Responsa by R. Joseph b. Moses (d. 1713) was born in Jerusalem, studied under Hezekiah b. David da Silva, then settled in Hebron with his father, and was apparently a Hebron emissary to Europe in 1689. From Hebron, Joseph went to Egypt and served as av bet din in Cairo. His responsa and novellae were published after his death by his son-in-law Joshua Zein, according to the order of the Arba'ah Turim, under the title Matteh Yosef (2 pts., Constantinople, 1717–26); the numerical value of matteh is 54, which is the number of responsa. In them he discussed halakhic problems with contemporary scholars, especially with R. Abraham Blom, rabbi of Egypt.
