Ephraim //; (Hebrew: אֶפְרַיִם/אֶפְרָיִם, Standard Efráyim Tiberian ʾEp̄ráyim/ʾEp̄rāyim) was, according to the Book of Genesis, the second son of Joseph and Asenath. Asenath was an Egyptian woman whom Pharaoh gave to Joseph as wife, and the daughter of Potipherah, a priest of On. Ephraim was born in Egypt before the arrival of the children of Israel from Canaan.
The Book of Numbers lists three sons of Ephraim: Shuthelah, Beker, and Tahan. However, 1 Chronicles 7 claims that he had at least eight sons, including Ezer and Elead, who were killed by local men who came to rob him of his cattle. After their deaths he had another son, Beriah. He was the ancestor of Joshua, son of Nun, the leader of the Israelite tribes in the conquest of Canaan.
