The prophecy becomes still more definite when the Lord begins to prepare the way for the appearance of this deliverance, by separating from the corrupt mass a single individual--Abraham--in order to make him the depositary of His revelations. The Lord, moreover, according to the good pleasure of His will, further specifies which of the descendants of Abraham, to the exclusion of all the rest, is to inherit this dignity, with all its accompanying blessings. From among the posterity of Shem, the Lord sets apart first the family of Abraham, then that of [12] Isaac, and lastly that of Jacob, as the family from which salvation is to come. Yet even these predictions, distinct though they be when compared with those previously uttered, are still very indefinite when compared with those subsequently given, and when seen in the light of the actual fulfilment. Even in these, the blessing only is foretold, but not its author. It still remained a matter of uncertainty whether salvation should be extended to all the other nations of the earth through a single individual, or through an entire people descended from the Patriarchs. The former is obscurely indicated; but the mode in which the blessing was to be imparted was left in darkness. This obscurity is partially removed by the last Messianic prophecy contained in Gen. xlix. 10. After what had previously taken place, we might well expect that the question as to which of Jacob's twelve sons should have the privilege of becoming the source of deliverance to the whole earth, would not be left undetermined; nor could we imagine that Jacob, when, just before his death, and with the spirit of a prophet, he transferred to his sons the promises which had been given to his ancestors and himself, should have passed over in silence the most important part of them. On the contrary, by being transferred to Judah, the promise of the Messiah acquires not only the expected limitation, but an unexpected increase of clearness and precision. Here, for the first time, the _person_ of the Messiah is brought before us; here also the _nature_ of His kingdom is more distinctly pointed out by His being represented as the peaceful one, and the peacemaker who will unite, under His mild sceptre, all the nations of the whole earth. Judah is, in this passage, placed in the centre of the world's history; he shall obtain dominion, and not lose it until it has been realized to its fullest extent by means of the _Shiloh_ descending from him, to whom all the nations of the earth shall render a willing obedience.
