God's Wife of Amun was the highest-ranking priestess of the Amun cult, an important religious institution in ancient Egypt. The cult was centered in Thebes in Upper Egypt during the Twenty-fifth and Twenty-sixth dynasties. The office had political importance as well as religious, since the two were closely related in ancient Egypt.

A priest is a religious leader authorized to perform the sacred rituals of a religion, especially as a mediatory agent between humans and one or more deities. They also have the authority or power to administer religious rites; in particular, rites of sacrifice to, and propitiation of, a deity or deities. Their office or position is the "priesthood", a term which also may apply to such persons collectively. A priest may have the duty to hear confessions periodically, give marriage counseling, provide prenuptial counseling, give spiritual direction, teach catechism, or visit those confined indoors, such as the sick in hospitals and nursing homes.
