Ephraim
In the prophetic books "Ephraim" and "Israel" are the collective names of the ten tribes who, under Jeroboam, established the northern kingdom, subsequently called Samaria (1 Kings 16:24) and were (B.C. 722) sent into an exile which still continues. (2 Kings 17:1-6).
They are distinguished as "the outcasts of Israel" from "the dispersed of Judah." (Isaiah 11:12). "Hidden" in the world (Matthew 13:44) they, with Judah, are yet to be restored to Palestine and made one nation again. (Jeremiah 23:5-8); (Ezekiel 37:11-24).
