Isaiah 59:21

This is my covenant, or what I have promised, and so am engaged to see fulfilled, viz. to them that turn from their iniquity; or rather, the promise of his word and Spirit to abide in his church, upon which account it is also that the Spirit is promised in the next words, by which is understood either the gift of prophecy, or the prophecy itself, given here to Isaiah, and so to the church: and being here, as in the foregoing verse, explicative, not copulative; unless it note that in an ordinary way the Spirit and the word go together wherever either of them are effectual, the Spirit impressing what the word expresses, 1 Thessalonians 14:16\\, and it is the spirit of Satan that is different from the word. My Spirit that is upon thee. See Poole on "Numbers 11:17", See Poole on "Numbers 11:25", &c.; See Poole on "2 Kings 2:15". Which I have put in thy mouth; which thou hast uttered by virtue of my Spirit, it being the church's great treasure and happiness to have God present with his word. Shall not depart out of thy mouth, &iowa.; the sense is either, these words, and the fulfilling of them, shall be always talked of, wherever the mention of this deliverance shall come, as is said of Mary's ointment, Matthew 26:13. Or rather, he seems to promise the perpetual presence of his word and Spirit with the prophets, apostles, and ministers, and teachers of the church to all succeeding ages thereof, and may have a special reference to the gospel, or new covenant in Christ. For ever, i.e. for a long, though yet a definitive, space of time, as it is often used.
