Animals often play a symbolic role in literature, sometimes as personified characters themselves, and sometimes through their frequent association with a human character. In Parashat Hayyei Sarah, wherever Rebecca goes, camels seem to follow her—and we begin to understand they have something to do with her.  They will function as the vehicle for finding her and then bringing her back to the land of Canaan, and they will even serve as the key figures in determining whether she is the right partner for Isaac and the next matriarch in the covenant.
