Tims right but know we are talking replacement theory Red the southern tribes of Israel made up of the largest tribe called Judah and Benjamin with some Levite's priests and are called Judah (todays Jews) in scripture as I said because it was the largest tribe Where you see in scripture when God mentions Judah and Ephraim (Manasseh) mentioned seperatley God is talking about Todays christian Nations (Ephraim/ Manasseh) and todays Jews(Judah) (the other smaller tribes spread across Europe)All twelve tribes together are called House of Israel. God knows where are his children are even if we have forgottenThese are what God calls the two sticks of his children they are divided and when Christ returns he will reunite them into one stick you can read of this in Eze. 37Eze 37:19 Say unto them, Thus saith the Lord GOD; Behold, I will take the stick of Joseph, which [is] in the hand of Ephraim, and the tribes of Israel his fellows, and will put them with him, [even] with the stick of Judah, and make them one stick, and they shall be one in mine hand. Eze 37:20 And the sticks whereon thou writest shall be in thine hand before their eyes. Eze 37:21 And say unto them, Thus saith the Lord GOD; Behold, I will take the children of Israel from among the heathen, whither they be gone, and will gather them on every side, and bring them into their own land: Eze 37:22 And I will make them one nation in the land upon the mountains of Israel; and one king shall be king to them all: and they shall be no more two nations, neither shall they be divided into two kingdoms any more at all:This one king is Christ at his return and the kingdoms here are Jew, and Christians under Christ
