Matthew Poole and continuators on Hebrews 6:19

19 Which hope we have as an anchor of the soul, both sure and stedfast , and which entreth into that within the veil .

Which, taketh in both the Good hoped for, and the Grace and Act it self of Hope exercised about it; which Grace is by a Metaphor set out to be to the Soul, what an Anchor is to Ships in a Tempest, when tossed with Gusts, and Storms, and Billows of Thoughts rouling one upon another to the oversetting of it; this Hope staieth, strengthens, setleth it, even the Hope and Certainty of eternal Rest and Happiness secured to them by the Promise and Oath of God. This Hope is safe and firm efficiently, and makes the Soul in the midst of all the threatning Temptations from a tempestuous World, safe; because fastned on God's Promise; and firm, because strengthned by God's Oath, which will hold out all Tempests.

This Hope, like an Anchor, is firmly placed, hath wrought it self into the best Holdfast, even the innermost part of the Veil. The Veil was that in the Tabernacle and Temple, which separated the holy Place from the Holy of Holiest. This typical Veil was rent at the Death of Christ, and the Holy of Holiest in Heaven, the Truth of that Type, was then laid open unto all Believers, whether Iews or Gentiles; comp. 9.24. and ch. 10.19, 20, 21. Here it is that the Anchor of the Christians Hope is fastned; this sure Harbour, where no Tempest can reach or loosen it, but into which their Souls, after all their tossings in the tempestuous Ocean of this World, by the Hurricanes of Temptations, which made them quiver again, shall be over, will enter with a full Gale, and injoy that Rest and Blessedness for ever, which they had by God's Promise and Oath on which they relied, secured to them. See Colos. 1.5. and 1 Pet. 1.3, 4, to 10.
