Isaiah 11:6

The fruit of righteousness is peace, which now reigns in humanity under the rule of the Prince of Peace, and even in the animal world, with nothing whatever to disturb it. "And the wolf dwells with the lamb, and the leopard lies down with the kid; and calf and lion and stalled ox together: a little boy drives them. And cow and bear go to the pasture; their young ones lie down together: and the lion eats shopped straw like the ox. And the suckling plays by the hole of the adder, and the weaned child stretches its hand to the pupil of the basilisk-viper. They will not hurt nor destroy in all my holy mountain: for the land is filled with knowledge of Jehovah, like the waters covering the sea." The fathers, and such commentators as Luther, Calvin, and Vitringa, have taken all these figures from the animal world as symbolical. Modern rationalists, on the other hand, understand them literally, but regard the whole as a beautiful dream and wish. It is a prophecy, however, the realization of which is to be expected on this side of the boundary between time and eternity, and, as Paul has shown in Rom 8, is an integral link in the predestined course of the history of salvation (Hengstenberg, Umbreit, Hofmann, Drechsler). There now reign among irrational creatures, from the greatest to the least, - even among such as are invisible, - fierce conflicts and bloodthirstiness of the most savage kind. But when the Son of David enters upon the full possession of His royal inheritance, the peace of paradise will be renewed, and all that is true in the popular legends of the golden age be realized and confirmed. This is what the prophet depicts in such lovely colours. The wolf and lamb, those two hereditary foes, will be perfectly reconciled then. The leopard will let the teazing kid lie d…

It is a very good transition in prophecy (whether it be so in rhetoric or no), and a very common one, to pass from the prediction of the temporal deliverances of the church to that of the great salvation, which in the fulness of time should be wrought out by Jesus Christ, of which the other were types and figures, to which all the prophets bore witness; and so the ancient Jews understood them. For what else was it that raised so great an expectation of the Messiah at the time he came. Upon occasion of the prophecy of the deliverance of Jerusalem from Sennacherib, here comes in a prophecy concerning Messiah the Prince. I. His rise out of the house of David (Isa 11:1). II. His qualifications for his great undertaking (Isa 11:2, Isa 11:3). III. The justice and equity of his government (Isa 11:3-5). IV. The peaceableness of his kingdom (Isa 11:6-9). V. The accession of the Gentiles to it (Isa 11:10), and with them the remnant of the Jews, that should be united with them in the Messiah's kingdom (Isa 11:11-16) and of all this God would now shortly give them a type, and some dark representation, in the excellent government of Hezekiah, the great peace which the nation should enjoy under him, after the ruin of Sennacherib's design, and the return of many of the ten tribes out of their dispersion to their brethren of the land of Judah, when they enjoyed that great tranquility.

11:6 In that day means in the coming age of the Messiah. The prophecy that follows received partial fulfillment in Isaiah’s day or shortly thereafter. The final fulfillment is found in the coming of the Messiah to inaugurate and then fully establish the age to come.
