This chapter treats of the comforts of God's people; of the forerunner and coming of the Messiah; of his work, and the dignity of his person; of the folly of making idols, and of the groundless complaints of the church of God.
The consolations of God's people, by whom to be administered, and the matter, ground, and reason of them, Isa 40:1. John the Baptist, the harbinger of Christ, is described by his work and office, and the effects of it; it issuing in the humiliation of some, and the exaltation of others, and in the revelation of the glory of Christ, Isa 40:3, then follows an order to every minister of the Gospel what he should preach and publish; the weakness and insufficiency of men to anything that is spiritually good; their fading and withering goodliness, which is to be ascribed to the blowing of the Spirit of God upon it; and the firmness and constancy of the word of God is declared, Isa 40:6, next the apostles of Christ in Jerusalem are particularly exhorted to publish fervently and openly the good tidings of the Gospel; to proclaim the coming of Christ, the manner of it, and the work he came about; and to signify his faithful discharge of his office as a shepherd, Isa 40:9, the dignity of whose person is set forth by his almighty power, by his infinite wisdom, and by the greatness of his majesty, in comparison of which all nations and things are as nothing, Isa 40:12 and then the vanity of framing any likeness to God, and of forming idols for worship, is observed, Isa 40:18, and from the consideration of the divine power in creation and upholding all things, the church of God is encouraged to expect renewed strength and persevering grace, and is blamed for giving way to a distrustful and murmuring spirit, Isa 40:26.
Ver. 1. Comfort ye, comfort ye my people, saith your God. The Babylonish captivity being predicted in the preceding chapter, for the comfort of God's people a deliverance is promised, expressed in such terms, as in the clearest and strongest manner to set forth the redemption and salvation by Jesus Christ, of which it was typical.
Here begins the more evangelical and spiritual part of this prophecy, which reaches to and includes the whole Gospel dispensation, from the coming of John the Baptist to the second coming of Christ. It begins with comforts, and holds on and ends with them; which consolations, Kimchi observes, are what should be in the times of the Messiah; and the word "comfort" is repeated, he says, to confirm the thing.
It is God that here speaks, who is the God of all comfort; the persons whom he would have comforted are his "people", whom he has chosen, with whom be has made a covenant in Christ, whom he has given to him, and he has redeemed by his blood, and whom he effectually calls by his grace; these are sometimes disconsolate, by reason of the corruptions of their nature, the temptations of Satan, the hidings of God's face, and the various afflictions they meet with; and it is the will of God they should be comforted, as appears by sending his Son to be the comforter of them, by giving his Spirit as another comforter, by appointing ordinances as breasts of consolation to them, by the promises he has made to them, and the confirmation of them by an oath, for their strong consolation; and particularly by the word of the Gospel, and the ministers of it, who are Barnabases, sons of consolation, who are sent with a comfortable message, and are encouraged in their work from the consideration of God being their God, who will be with them, assist them, and make their ministrations successful; and to these are these words addressed; which are repeated, not to suggest any backwardness in Gospel ministers, who are ready to go on such an errand, however reluctant they may be to carry bad tidings; but rather to signify the people's refusal to be comforted, and therefore must be spoken to again and again; and also to show the vehement and hearty desire of the Lord to have them comforted.
The Targum is,"O ye prophets, prophesy comforts concerning my people.''And the Septuagint and Arabic versions insert, "O ye priests", as if the words were directed to them.
