Israel (Joseph-Ephraim) received the birthright, not Judah (1 Chronicles 5:1-2). The Two Houses are separate peoples with separate promises (Genesis 49; Deuteronomy 33) even in the end-time (Revelation 7). This separation went back to Genesis 38:1, continued in the time of Moses and the Exodus (Psalm 114:1-2), continuing until their rejoining by faith in David’s Greater Son, the Messiah, at the end of age (Ezekiel 37:22-25). The Old Testament distinguishes them, most notably in the Books of Kings and Chronicles & New Testament, Matthew 10:6; 15:24. www.migrations.info
