Matthew Poole and continuators on Isaiah 59:21

21 And as for me, this is my covenant with them, saith the LORD, My spirit that is upon thee , and my words which I have put in thy mouth , shall not depart out of thy mouth, nor out of the mouth of thy seed, nor out of the mouth of thy seeds seed , saith the LORD, from henceforth and for ever .

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, Ioh. 14. 10, 17, 26. and it is the Spirit of Satan, that is different from the word.

See on Num. 11. 17, 25, &c. & 2 Kin. 2. 15.

Which thou hast uttered by vertue of my Spirit, it being the Churches great treasure, and happiness to have God present with his word.

The sense is either, these words, and the fulfilling of them shall be alwaies talked of wherever the mention of this deliverance shall come, as is said of [illegible: 1 word] ointment, Mat. 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.

i. e. for a long, though yet a definitive space of time, as it is often used.
