Step-by-step explanation:
The bar mitzvah of Abraham and Hazel's nephew is an example of a religious rite of passage. A rite of passage is a ritual designed to mark the transition of individuals between different stages of life. In the case of a bar mitzvah in the Jewish tradition, it celebrates the transition of a boy into adulthood, effectively marking his new social and religious responsibilities within the community. Such ceremonies often involve three stages as identified by anthropologist Arnold van Gennep: separation, during which the individual leaves their original status; transition, where the individual is in a liminal state; and incorporation, the final phase where they are reintroduced into society with a new status.
