In Talmudic literature we occasionally run across a slight reference to the ten tribes, as, for instance, Mar Sutra's statement that they journeyed to Iberia, at that time synonymous with Spain, though the rabbi probably had northern Africa in mind. Another passage relates that the Babylonian scholars decided that no one could tell whether he was descended from Reuben or from Simon, the presumption in their mind evidently being that the ten tribes had become amalgamated with Judah and Benjamin. If they are right, if from the time of Jeremiah to the Syrian domination, a slow process of assimilation was incorporating the scattered of the ten tribes into the returned remnant of Judah and Benjamin, then the ten lost tribes have no existence, and we are dealing with a myth. But the question is still mooted. The prophets and the rabbis continually dwell upon the hope of reunion. The Pesikta is the first authority to locate the exile home of the ten tribes on the Sambation. A peculiarly interesting conversation on the future of the ten tribes between two learned doctors of the Law, Rabbi Akiba and Rabbi Eliezer, has been preserved. Rabbi Eliezer maintains: "The Eternal has removed the ten tribes from their soil, and cast them forth into another land, as irrevocably as this day goes never to return." Rabbi Akiba, the enthusiastic nationalist, thinks very differently: "No, day sinks, and passes into night only to rise again in renewed brilliance. So the ten tribes, lost in darkness, will reappear in refulgent light."
