Binyamin Hatzadik, whose grave is in Tsefat according to Rabbi Chaim Vital in the name of the Ari Zal, is mentioned only one time in our sources.
The gemara tells of the time that a woman came to him, as manager of a charity fund, for help during a drought. When he informed her that there was no charity funds left she cried, "Rabbi, if you don't help me a woman and her seven sons will die!"
This tzadik was so moved by her plight that he gave her his own funds. Soon after he became deathly ill. In his behalf interceded angels who said to G-d: "Master of the Universe, You said that whoever sustains one life in Israel is considered as if he saved the entire world. Binyamin Hatzadik supported a woman and her seven sons. Must he die at a young age?"
The decree of death was rescinded and twenty-two years were added to his life.
