I dont think God really cares much about the ancient house of Israel.
(Psa 78:67) Moreover he refused the tabernacle of Joseph, and chose not the tribe of Ephraim:
(Psa 78:68) But chose the tribe of Judah, the mount Zion which he loved.
Doesnt look like Ephraim exists anymore.
(Isa 7:5) Because Syria, Ephraim, and the son of Remaliah, have taken evil counsel against thee, saying,
(Isa 7:6) Let us go up against Judah, and vex it, and let us make a breach therein for us, and set a king in the midst of it, even the son of Tabeal:
(Isa 7:7) Thus saith the Lord GOD, It shall not stand, neither shall it come to pass.
(Isa 7:8) For the head of Syria is Damascus, and the head of Damascus is Rezin; and within threescore and five years shall Ephraim be broken, that it be not a people.
Seems they've been utterly taken away...
(Hos 1:4) And the LORD said unto him, Call his name Jezreel; for yet a little while, and I will avenge the blood of Jezreel upon the house of Jehu, and will cause to cease the kingdom of the house of Israel.
(Hos 1:5) And it shall come to pass at that day, that I will break the bow of Israel in the valley of Jezreel.
(Hos 1:6) And she conceived again, and bare a daughter. And God said unto him, Call her name Loruhamah: for I will no more have mercy upon the house of Israel; but I will utterly take them away.
(Hos 1:7) But I will have mercy upon the house of Judah, and will save them by the LORD their God, and will not save them by bow, nor by sword, nor by battle, by horses, nor by horsemen.
Looks like they unified when they came up out of the land, thats probably why there is no ancient House of Israel anymore...
(Hos 1:11) Then shall the children of Judah and the children of Israel be gathered together, and appoint themselves one head, and they shall come up out of the land: for great shall be the day of Jezreel.
Yup...definately already unified, look at this...its the return from babylon...
(Eze 37:16) Moreover, thou son of man, take thee one stick, and write upon it, For Judah, and for the children of Israel his companions: then take another stick, and write upon it, For Joseph, the stick of Ephraim, and for all the house of Israel his companions:
(Eze 37:17) And join them one to another into one stick; and they shall become one in thine hand.
(Eze 37:18) And when the children of thy people shall speak unto thee, saying, Wilt thou not shew us what thou meanest by these?
(Eze 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:
