Question (composite of several): Is it not true that 10 of the 12 tribes of Israel have been lost and that those known as Jews today are only from the tribes of Judah and Benjamin? If so, what happened to them and how can God bring all 12 tribes back to their land in the last days?

Response: If the 10 tribes were lost through intermarriage, then they can't be recovered. In that case, the Lord cannot fulfill His promise to bring all Israel back to her land (Jer:32:37-42 [37] Behold, I will gather them out of all countries, whither I have driven them in mine anger, and in my fury, and in great wrath; and I will bring them again unto this place, and I will cause them to dwell safely: [38] And they shall be my people, and I will be their God: [39] And I will give them one heart, and one way, that they may fear me for ever, for the good of them, and of their children after them: [40] And I will make an everlasting covenant with them, that I will not turn away from them, to do them good; but I will put my fear in their hearts, that they shall not depart from me. [41] Yea, I will rejoice over them to do them good, and I will plant them in this land assuredly with my whole heart and with my whole soul. [42] For thus saith the LORD; Like as I have brought all this great evil upon this people, so will I bring upon them all the good that I have promised them.

[18] And when the children of thy people shall speak unto thee, saying, Wilt thou not shew us what thou meanest by these? [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.

It is a myth that the 10 tribes which were taken captive into Assyria (2 Kings:17:6-23 [6] In the ninth year of Hoshea the king of Assyria took Samaria, and carried Israel away into Assyria, and placed them in Halah and in Habor by the river of Gozan, and in the cities of the Medes. [7] For so it was, that the children of Israel had sinned against the LORD their God, which had brought them up out of the land of Egypt, from under the hand of Pharaoh king of Egypt, and had feared other gods, [8] And walked in the statutes of the heathen, whom the LORD cast out from before the children of Israel, and of the kings of Israel, which they had made. [9] And the children of Israel did secretly those things that were not right against the LORD their God, and they built them high places in all their cities, from the tower of the watchmen to the fenced city. [10] And they set them up images and groves in every high hill, and under every green tree: [11] And there they burnt incense in all the high places, as did the heathen whom the LORD carried away before them; and wrought wicked things to provoke the LORD to anger: [12] For they served idols, whereof the LORD had said unto them, Ye shall not do this thing. [13] Yet the LORD testified against Israel, and against Judah, by all the prophets, and by all the seers, saying, Turn ye from your evil ways, and keep my commandments and my statutes, according to all the law which I commanded your fathers, and which I sent to you by my servants the prophets. [14] Notwithstanding they would not hear, but hardened their necks, like to the neck of their fathers, that did not believe in the LORD their God. [15] And they rejected his statutes, and his covenant that he made with their fathers, and his testimonies which he testified against them; and they followed vanity, and became vain, and went after the heathen that were round about them, concerning whom the LORD had charged them, that they should not do like them. [16] And they left all the commandments of the LORD their God, and made them molten images, even two calves, and made a grove, and worshipped all the host of heaven, and served Baal. [17] And they caused their sons and their daughters to pass through the fire, and used divination and enchantments, and sold themselves to do evil in the sight of the LORD, to provoke him to anger. [18] Therefore the LORD was very angry with Israel, and removed them out of his sight: there was none left but the tribe of Judah only. [19] Also Judah kept not the commandments of the LORD their God, but walked in the statutes of Israel which they made. [20] And the LORD rejected all the seed of Israel, and afflicted them, and delivered them into the hand of spoilers, until he had cast them out of his sight. [21] For he rent Israel from the house of David; and they made Jeroboam the son of Nebat king: and Jeroboam drave Israel from following the LORD, and made them sin a great sin. [22] For the children of Israel walked in all the sins of Jeroboam which he did; they departed not from them; [23] Until the LORD removed Israel out of his sight, as he had said by all his servants the prophets. So was Israel carried away out of their own land to Assyria unto this day.

See All..., long after the carrying away of Israel into Assyria, we read of King Josiah cleansing from idolatry "the cities of Manasseh, and Ephraim, and Simeon, even unto Naphtali." In 34:9-10 there is mention of the offering to repair the temple that was given by "Manasseh and Ephraim, and of all the remnant of Israel. . . ." In 35:17-18 we read that the passover in Jerusalem was attended by "the children of Israel . . . [and] all Judah and Israel."

Obviously, not every member of the 10 tribes was carried captive into Assyria, and many must have made their way back to Israel in the ensuing years. Furthermore, since God said that He would scatter Israel into all the world and bring her back to her land in the last days, why should 10 tribes be lost simply because they were taken to Assyria? Here is His Word: "For, lo, I will command, and I will sift the house of Israel [not just Judah and Benjamin] among all nations, like as corn is sifted in a sieve, yet shall not the least grain fall upon the earth" (Am 9:9).

Those known today as Jews are not only from the tribes of Benjamin and Judah but from all Israel. We have God's Word for that, otherwise He could not bring them back to their land. Here is only one of scores of promises: "And I will bring again the captivity of my people of Israel, and they shall build the waste cities, and inhabit them; . . . and they shall no more be pulled up out of their land which I have given them saith the LORD thy God" (Amos:9:14-15 [14] And I will bring again the captivity of my people of Israel, and they shall build the waste cities, and inhabit them; and they shall plant vineyards, and drink the wine thereof; they shall also make gardens, and eat the fruit of them. [15] And I will plant them upon their land, and they shall no more be pulled up out of their land which I have given them, saith the LORD thy God.
