1. The “city of the Sun,” in Egypt. Poti-pherah, the father of Asenath, Joseph’s wife, was priest of the city (Gen. 41:45,50; Gen. 46:20). It is regarded as the same as BETH-SHEMESH in Jeremiah 43:13, and as AVEN in Ezekiel 30:17; and is supposed to be alluded to in Isaiah 19:18 (see margin). Identified with the ruins of Heliopolis, 30° 8' N, 31° 23' E: about ten miles N.E. of Cairo. On has been found in the inscriptions as AN and AN-T.
2. Son of Peleth, a Reubenite: he joined with Korah in murmuring against Moses and Aaron (Num. 16:1). He is not mentioned after verse 1. The Jews say he separated from the guilty company and was saved.
