Isaías 2:4

He shall judge among the nations. — For “rebuke” read decide or arbitrate. The ideal Divine King is to be all, and more than all, that Solomon had been (1 Reis 10:24). In reliance on His wisdom and equity, nations would refer their disputes to His decision instead of the arbitrament of war. Here again we have a partial fulfilment, it may be hoped, a “springing and germinant accomplishment,” in the history of Christendom. So far as the teaching of Christ has influenced international polity and law, He has been the supreme arbitrator of their disputes.

And they shall beat their swords into plowshares. — The words invert the picture of an earlier prophet, who spoke of a time of war (Joel 3:10). Isaiah must have known that prediction, and yet he proclaims (following Oséias 2:18) that peace, not war, is the ideal goal towards which the order of the Divine government is tending. (Comp. Zacarias 9:10; Lucas 2:14.)
