(21) As for me, this is my covenant . . .--The words are, as to their form, an echo of Genesis 17:4; as to their meaning, the germ of Jeremiah 31:31; Hebrews 8:10; Hebrews 10:16. The new covenant is to involve the gift of the Spirit, that writes the law of God inwardly in the heart, as distinct from the Law, which is thought of as outside the conscience, doing its work as an accuser and a judge. Verse 21. - As for me; literally, and I. The prophet begins with one construction, and then checks himself, and introduces another. This is my covenant (comp. Jeremiah 31:31-34; and see the comment on Isaiah 53:3). The new covenant involved the giving of God's Spirit to his people (Joel 2:28); and this Spirit, it is here promised, shall not depart from God's people while time endures. The Spirit will be accompanied with certain "words" which will be put into the Church's mouth; and these words will remain unchanged and pass on from mouth to mouth, age after age, for ever. The "words" intended are probably those of the entire Bible - "all God's revelations" (Cheyne) - which the Church will maintain as inspired truth through all ages. Upon thee; i.e. upon Israel. The change of number and person ("with them... upon thee") is not unusual in Isaiah (Isaiah 1:29; Isaiah 33:2; Isaiah 49:5; Isaiah 62:11, 12, etc.). my Spirit which is upon thee, and my words which I have put in thy mouth; the Spirit of God, with his gifts and graces, which were upon Christ the Redeemer without measure; and the doctrines he received from his divine Father to teach others, and which he gave to his apostles; the same Spirit which in measure was put upon them, and the same truths which were delivered to them: shall not depart out of thy mouth, nor out of the mouth of thy seed, nor out of the mouth of thy seed's seed, saith the Lord, from henceforth and for ever; that is, shall always continue with the church and her spiritual seed, such as are born in her, and brought up by her, throughout all successive ages, and to the end of time; and it may be observed, that after the conversion of the Jews, to which this prophecy has a special regard, they shall no more apostatize; the Spirit of the Lord shall not depart from them; and the Gospel shall always be professed by them: and it may be further observed, that the Spirit and the word go together; and that the latter is only effectual as accompanied will, the former, and is a proof of the perseverance of the church of God, and of all such who have the Spirit and grace of God, Christ will always have a church, and that church a seed, in which the Spirit and word will always remain. The grace of the Spirit, in the hearts of God's people, never removes from them; nor his Gospel from such, in whose hearts it works effectually. The Targum interprets this of the words of prophecy; and the Talmud (o) of the law not departing from the disciples of wise men; but it is best to understand it of the Gospel not departing from the disciples of Christ, and the seed of the church.
