God shall enlarge Japheth. — First, the Deity is here Elohim, following upon Jehovah in the preceding verse, and that with extraordinary exactness. Jehovah has never been the special name of the Deity worshipped by the race of Japheth, though doubtless it is the Greek Zeus and the Latin Jove. But it soon became the proper title of God in covenant with the race of Shem. It is plainly impossible to divide this most ancient poem into Elohistic and Jehovistic sections, and the theory, however plausible occasionally, fails in a crucial place like this. Next, there is a play upon the name of Japheth, or rather, Yepheth, our translators having made the same mistake as in changing Hebel into Abel. The Hebrew is Yapheth Elohim l’Yepheth, “God enlarge the enlarger” (not “God shall enlarge”). While, then, it is the special blessing of Shem that through him the voice of thanksgiving is to ascend to Jehovah, the God of grace; it is Elohim, the God of nature and of the universe, who gives to Japheth wide extension and the most numerous posterity. If the most ancient civilisation and the earliest empires in Egypt and on the Tigris were Hamite, the great world- powers of history, the Chaldean, the Medo-Persian, the Greek and Roman, the Hindoo, were all of Japhetic origin, as are also the modern rulers of mankind.
He shall dwell in the tents of Shem. — (Rather, let him dwell). In one sense Shem now dwells in the tents of Japheth: for the Jews, the noblest representatives of Shem, dwell dispersed in Aryan countries; and except in the Arabian peninsula, once Cushite, the Shemites have no home of their own. But the religious privileges of their race now belong to the family of Japheth. Carried by Jewish missionaries, like St. Paul, throughout the Roman world, they have become the property of the leading members of the Aryan race; and thus Japheth takes possession of the tents which by right of primogeniture belonged to Shem. For “to dwell in the tents of Shem” is not so much to share them as to own them; and if the Jews retain some degree of faith, it has lost with them all expansive power; while the right interpretation of their Scriptures, and as well the maintenance as the propagation of the religion of their Messiah, are now in the hands of the descendants of Japheth. Yet Shem does not lose all pre-eminence: for again we read —
Canaan shall be his servant (rather, their). — If Shem lose the foremost place of primogeniture, he is still a brother, and Canaan but a slave.
