Matthew Poole and continuators on Hebrews 8:13

13 In that he saith, A new Covenant, he hath made the first old ; Now that which decayeth and waxeth old, is ready to vanish away .

The Inference from what was before said, ver. 8. (In the Lord's saying this by the Prophet Ieremiah, that he would make a new Covenant for form and manner of administration, later and better, even the last and best he will make, and in which he will have penitent, believing Sinners to acquiesce) is this, That the Mosaical one, though first in respect of the Gospel, hath lost its power, strength and vigour, its binding force; and so by God's instituting another, is abrogated as useless, needless and imperfect.

This Mosaical one thus grown old, weak and decrepit, and by the institution of the new Gospel-Covenant, abrogated, may continue for a while, but in no force; and so gradually moulder and decay by little and little, till it at last vanish and totally cease: It was near to it upon finishing of the Ministry of the Gospel-High-Priest on Earth, when by his Death he fulfilled the Truth of this Typical one, and so virtually nulled it; and as to its binding force, vanished, when the Gospel was published throughout the World: Rom. 10.16, 17, 18. compare 2 Cor. 5.1[illegible: 1 letter]. as is owned by the Apostolical Synod, Acts ch. 15. It was high time for these Hebrews to cease from that Vanishing Mosaical one; and effectually to close with the Gospel-Priesthood and Covenant, which must remain and continue for ever; see Dan. 9.24, 26, 27. which if they did not, must end in the total destruction of them, their Temple and City; which came to pass not many years after the Apostle wrote this Epipistle.
