POTIPHERA pə tĭf’ ə rə (פֹּ֥וטִי פֶ֛רַע). The father-in-law of Joseph (Gen 41:45). He is referred to as a priest of On (Heliopolis), the center of the worship of the sun-god, Re’. The fact that outside of the Bible this name has not been discovered in Egypt earlier than c. the 10th cent. b.c. is no sure proof that the Genesis story is of a late date.
