The wolf also shall dwell with the lamb, and the leopard shall lie down with the kid; and the calf and the young lion and the fatling together; and a little child shall lead them.
All Commentaries on Isaiah 11:6 Go To Isaiah 11
John Chrysostom
AD 407
When he says, “Every valley shall be filled, and every mountain and hill shall be brought low, and the rough ways shall be made smooth,” he is signifying the exaltation of the lowly, the humiliation of the self-willed, the hardness of the law changed into easiness of faith. For it is no longer toils and labors, says he, but grace and forgiveness of sins, affording great facility of salvation. Next he states the cause of these things, saying, “All flesh shall see the salvation of God,” no longer Jews and proselytes only, but also all earth and sea and the entire human race. Because by “the crooked things” he signified our whole corrupt life, publicans, harlots, robbers, magicians, as many as having been perverted before afterwards walked in the right way: much as he himself likewise said, “Publicans and harlots go into the kingdom of God before you,” because they believed. And in other words also again the prophet declared the selfsame thing, thus saying, “Then wolves and lambs shall feed together.” For similarly here by the hills and valleys, he meant that incongruities of character are blended into one and the same evenness of self-restraint, so also there, by the characters of the brute animals indicating the different human dispositions, he again spoke of their being linked in one and the same harmony of godliness.
