Choni Hamagel was a Jewish Sage living in the 1st century BCE during the leadership of the last three sets of Zugot. When drought came upon the land, Choni drew a circle and vowed he would not step out until Hashem answered his prayers for rain. When his request was answered, Choni kept on redefining it. He said the rains where too light or two strong. Shimon ben Shatach sent a message that he would have excommunicated Choni if it were it not clear that Choni had a special relationship with Hashem.

Choni Hameagel is buried in the city of Chatzor, Northern Israel. His actual grave is in the cave section of the tomb. Since the actual cave is kept locked most of the time, a Tziyun was built in the outside room where people come and pray. There is an opinion that his two grandchildren Abba Chilkia and Chanan Hanecheba are buried with him in the cave. However most sources disagree and place them either in a cave at the foot of the hill or on top of the nearby mountain. During years of drought, people come to Kever Choni Hamagel to beseech Hashem for rain.

Once the entire month of Adar had passed and still no rain came. Messengers were sent to Choni Hamagel, asking him to pray for rain. When Choni prayed and no rain came, he proceeded to draw a large circle in the dust of the ground with his staff. He then stood in middle of the circle and similar to what had been done by the prophet Chavakuk, he swore in Hashem's great name that since his sons had approached him considering him to have inside connections, he would not leave the circle until Hashem had mercy on them and it began to rain.

The observed Yahrtziet of of Choni Hameagel is on 5th of Iyyar. on this day Chatzor locals come to the Kever to celebrate the Hillulah.;
