The term 'ISIS Husband' refers to the Egyptian god Osiris, who was the husband of Isis. Osiris was a major deity in ancient Egyptian religion and was the god of the afterlife, the underworld, and rebirth. He was also associated with fertility, agriculture, and the cycle of Nile floods. Osiris was murdered by his brother Set, but was resurrected by Isis, who used her magical powers to bring him back to life.
