Nephthys was typically paired with her sister Isis in funerary rites because of their role as protectors of the mummy and the god Osiris and as the sister-wife of Set.

In the funerary role, Nephthys often was depicted as a kite or as a woman with falcon wings, usually outstretched as a symbol of protection. Nephthys’s association with the kite and its piercing, mournful cries evidently reminded the Egyptians of the lamentations usually offered for the dead by wailing women. She was, almost without fail, depicted as crowned by the hieroglyphics signifying her name, which were a combination of signs for the sacred temple enclosure along with the sign for mistress on top of the enclosure sign.

Nephthys was clearly viewed as a morbid-but-crucial force of heavenly transition, i.e., the pharaoh becomes strong for his journey to the afterlife through the intervention of Isis and Nephthys. The same divine power could be applied later to all of the dead, who were advised to consider Nephthys a necessary companion.
