No one could console the sorrowing Judæan community with such sympathy, or encourage it with such ardour as the Prophet of the Captivity. His words are like balm upon a burning wound, or like a gentle breeze upon a fevered brow.
"Comfort ye," he begins, "comfort ye, comfort ye my people, saith your God. Speak ye to the heart of Jerusalem, and cry unto her, that her warfare is accomplished, that her iniquity is pardoned; for she hath received of the Lord's hand double for all her sins." (Isaiah xl.)
The exhausted and despairing community was described by this prophet as a wife and mother who had been rejected, and robbed of her children on account of her sins, but who still is dear to her husband as the beloved of his youth. This deserted one he calls "Jerusalem," the emblem of all that was tender to his soul. He exclaims to the forlorn mother:
"Awake, awake, stand up, O Jerusalem, which hast drunk at the hand of the Lord the cup of his fury. Thou hast drunken the dregs of the cup of trembling and wrung them out.
"There is none to guide her among all the sons whom she hath brought forth, neither is there any that taketh her by the hand, of all the sons that she has brought up.... O thou afflicted, tossed with tempest, and not comforted, behold I will lay thy stones with fair colours, and lay thy foundations with sapphires, and I will make thy windows of agates, and thy gates of carbuncles, and all thy borders of precious stones, and all thy children shall be taught of the Lord, and great shall be the peace of thy children....
"As one whom his mother comforteth, so will I comfort you, and ye shall be comforted in Jerusalem."
But where is this consolation to be found? Not in the hope of vain, worldly glory, not in might and power, but in an all-embracing salvation. This prophet of the Captivity was the first who clearly grasped and demonstrated that a creed of general salvation was promised through Abraham to future generations. The past was to be forgotten and forgiven; a new social order was to spring up; heaven and earth were to be re-created. All people from all the ends of the earth would be included in this universal salvation, and every knee would bend and every tongue swear homage to the God adored by Israel. It was for this purpose that Abraham had been called from a distant land, and that his descendants had been chosen before their birth. God had created the people of Israel to be His servant among nations, His messenger to all people, His apostle from the beginning of the world.
The prophet describes this apostolic people in poetry of such transcendental beauty that it becomes an ideal. And is there any mission sublimer than that of being the vanguard of the nations in the path of righteousness and salvation? Was Israel not to be proud of having been chosen for such a duty? The prophet goes on to say how this ideal nation was to realise its apostolic mission:
"Behold my servant, whom I uphold, mine elect, in whom my soul delighteth; I have put my spirit upon him, he shall bring forth judgment to the Gentiles. He shall not cry, nor lift up, nor cause his voice to be heard in the street. A bruised reed shall he not break, and the smoking flax shall he not quench; he shall bring forth judgment into truth." (Isaiah xlii. 1–4.)
The Law of God was thus to be universally acknowledged, and the messenger of God was to bring about this acknowledgment by his own example, in spite of scorn, contempt, and persecution. This, Israel's recognised mission, the prophet of the Captivity explained briefly, in words supposed to be spoken by the nation itself (Isaiah xlix. 1–6). He taught that martyrdom, bravely encountered and borne with gentle resignation, would ensure victory to the law of righteousness, which Israel, if true to its ideals, was to promulgate. The leading conception that runs through Isaiah's poetical monologue was thus expressed by the prophet in the short but effective verse:
"For mine house shall be called an house of prayer for all peoples." (Isaiah lvi. 7.)
The fall of the Babylonian empire, with its absurd and immoral idolatry, and the deliverance of the Judæan community were to be the first steps in this great work of universal salvation. The fall of Babylon seemed indeed inevitable to the prophet, so that he spoke of it as of an accomplished fact, and not as a subject of prophetic vision.
