Sandek
A sandek or sandak (Hebrew: סנדק "companion of child", from Koinē Greek: σύντεκνος) is a person honored at a brit milah in Judaism, traditionally either by holding the baby boy on the knees or thighs when the mohel performs the circumcision or by handing the baby to the mohel.
In Modern Hebrew, sandak is also the word for godfather; the film The Godfather is known in Hebrew as HaSandak. The role is distinct from that of the kvater, a Yiddish term for the person who carries the baby in Ashkenazi ceremonies.
