_Upon the land of my people shall come up thorns and briers; yea, upon all the houses of joy in the joyous city: for the palace shall be forsaken; the populous city shall be deserted; Ophel and the Watch-tower shall be for dens for ever, a joy of wild asses, a pasture of flocks._ The attempt has been made to confine this reference to the outskirts of the sacred city, but it is hardly a just one. The prophet, though he does not name the city, evidently means Jerusalem, and means the whole of it. Some therefore deny the authenticity of the prophecy. Certainly it is almost impossible to suppose, that so definite a sentence of ruin can have been published at the same time as the assurances of Jerusalem's inviolability in the preceding orations. But that does not prevent the hypothesis that it was uttered by Isaiah at an earlier period, when, as in chaps. ii. and iii., he did say extreme things about the destruction of his city. It must be noticed, however, that Isaiah speaks with some vagueness; that at the present moment he is not concerned with any religious truth or will of the Almighty, but simply desires to contrast the careless gaiety of the women of Jerusalem with the fate hanging over them. How could he do this more forcibly than by turning the streets and gardens of their delights into ruins and the haunts of the wild ass, even though it should seem inconsistent with his declaration that Zion was inviolable? Licence for a certain amount of inconsistency is absolutely necessary in the case of a prophet who had so many divers truths to utter to so many opposite interests and tempers. Besides, at this time he had already reduced Jerusalem very low (xxix. 4). III. THE SPIRIT OUTPOURED (vv. 15-20). The rest of the prophecy is luminous rather than lucid, full of suffused rather than distinct meanings. The date of the future regeneration is indefinite--another feature more in harmony with Isaiah's earlier prophecies than his later. The cause of the blessing is the outpouring of the Spirit of God (ver. 15). Righteousness and peace are to come to earth by a distinct creative act of God. Isaiah adds his voice to the invariable testimony of prophets and apostles, who, whether they speak of society or the heart of individual man, place their hope in new life from above by the Spirit of the living God. Victor Hugo says, "There are no weeds in society, only bad cultivators;" and places all hope of progress towards perfection in proper methods of social culture. These are needed, as much as the corn, which will not spring from the sunshine alone, requires the hand of the sower, and the harrow. And Isaiah, too, speaks here of human conduct and effort as required to fill up the blessedness of the future: righteousness and labour. But first, and indispensably, he, with all the prophets, places the Spirit of God.
