On the other hand, it is to be observed that this individualism was not absolute. The people were arranged according to their families, and the names that distinguished the families were not those of the present heads of houses, but the names of ancestors, possibly of captives taken down to Babylon by Nebuchadnezzar. As some of these names occur in later expeditions, it is plain that the whole of the families they represented were not found in the first body of pilgrims. Still the people were grouped in family order. The Jews anticipated the modern verdict of sociology, that the social unit is the family, not the individual. Judaism was, through and through, a domestic religion. Further, it is to be noted that a sort of caste feeling was engendered in the midst of the domestic arrangement of the people. It emerges already in the second chapter of Ezra in the cases of families that could not trace their genealogy, and it bears bitter fruit in some pitiable scenes in the later history of the returned people. Not only national rights, but also religious privileges, come more and more to depend on purity of birth and descent. Religion is viewed as a question of blood relationship. Thus even with the very appearance of that new-born individualism which might be expected to counteract it, even when the recovered people is composed entirely of volunteers, a strong racial current sets in, which grows in volume until in the days of our Lord the fact of a man's being a Jew is thought a sufficient guarantee of his enjoying the favour of Heaven, until in our own day such a book as "Daniel Deronda" portrays the race-enthusiasm of the Israelite as the very heart and essence of his religion. We have three copies of the list of the returning exiles--one in Ezra ii., the second in Nehemiah vii., and the third in 1 Esdras v. They are evidently all of them transcripts of the same original register; but though they agree in the main, they differ in details, giving some variation in the names and considerable diversity in the numbers--Esdras coming nearer to Ezra than to Nehemiah, as we might expect. The total, however, is the same in every case, viz., 42,360 (besides 7337 servants)--a large number, which shows how important the expedition was considered to be.
