a city of Egypt, mentioned only by Ezekiel. ( Ezekiel 30:15 Ezekiel 30:16 ) The name is Hebrew, or at least Semitic, perhaps signifying clay . It is identified in the Vulgate with Pelusium, "the clayey or muddy" town. Its antiquity may perhaps be inferred from the mention of "the wilderness of Sin" in the journeys of the Israelites. ( Exodus 16:1 ; Numbers 33:11 ) Ezekiel speaks of Sin as "Sin the strongholds of Egypt." ( Ezekiel 30:15 ) This place was held by Egypt from that time until the period of the Romans. Herodotus relates that Sennacherib advanced against Pelusium, and that near Pelusium Cambyses defeated Psammenitus. In like manner the decisive battle in which Ochus defeated the last native king, Nectanebes, was fought near this city.
