According to the Hebrew Bible, the Tribe of Ephraim (Hebrew: אֶפְרַיִם / אֶפְרָיִם, Modern Efráyim Tiberian ʾEp̄ráyim / ʾEp̄rāyim ; "double fruitfulness") was one of the Tribes of Israel. The Tribe of Manasseh together with Ephraim also formed the House of Joseph. However, on the accession of Rehoboam, David's grandson, in c. 930 BC the northern tribes split from the House of David to reform a Kingdom of Israel as the Northern Kingdom. The first king of the Northern Kingdom of Israel was Jeroboam, who came from the Tribe of Ephraim. (1 Kings 11:26)
