There is not a ancient Egyptian word like "marry"; a union between equals was very important in Egyptian cultures, Isis and Osiris were equals and so joined as such. Osiris was the first son of Geb and Nut; and Isis the first daughter.
In Egyptian mythology, Osiris married Isis because she was his sister and also his true love. They were both part of the Ennead, a group of nine deities in ancient Egyptian religion, and their marriage symbolized stability, fertility, and the eternal cycle of life and death. Together, they ruled over Egypt and were beloved by the people for their wisdom and benevolence.

For Egyptian gods and goddesses, at least Osiris, Isis, Horus, Set, and Nepthys, it is sort of like reincarnation but not. So, originally Osiris, Isis, Horus, Set, and Nepthys were all brother and sister but then later on the story was told differently with Osiris and Set still being brothers and Osiris being married to Isis and Horus being their son while Set and Nepthys were married.
