This case is remarkable. From the stationary character of all things in the East, there was a probability beforehand, that several nations--as in particular, four that we will mention: the Greeks, the Egyptians, the Persians, the Affghans--should have presented the same purity of descent, untainted by alien blood, which we find in the children of Ishmael, and the children of his half-brother the patriarch Isaac. Yet, in that case, where would have been the miraculous unity of race predicted for these two nations exclusively by the Scriptures? The fact is, the four nations mentioned have been so profoundly changed by deluges of foreign conquest or foreign intrusion, that at this day, perhaps, no solitary individual could be found whose ancestral line had not been confounded with other bloods. The Arabs only, and the Jews, are under no suspicion of this hybrid mixture. Vast deserts, which insulate one side of the Arabian peninsula; the sea, which insulates the other sides, have, with other causes, preserved the Arab blood from all general attaint of its purity. Ceremonies, institutions, awful scruples of conscience, and through many centuries, misery and legal persecution, have maintained a still more impassable gulf between the Jews and other races. Spain is the only Christian land where the native blood was at any time intermingled with the Jewish; and hence one cause for the early vigilance of the Inquisition in that country more than elsewhere; hence also the horror of a Jewish taint in the Spanish hidalgo; Judaism masquing itself in Christianity, was so keenly suspected, or so haughtily disclaimed, simply because so largely it existed. It was, however, under a very peculiar state of society, that, even during an interval, and in a corner, Jews _could_ have intermarried with Christians. Generally, the intensity of reciprocated hatred, long oppression upon the one side, deep degradation upon the other, perpetuated the alienation, had the repulsion of creeds even relaxed. And hence, at this day, the intense purity of the Jewish blood, though probably more than six millions of individuals.
