For, lo, they that are far from thee shall perish: thou hast destroyed all them that go a whoring from thee. They that are far from thee shall perish - The term perish is generally used to signify a coming to nothing, being annihilated; and by some it is thus applied to the finally impenitent, they shall all be annihilated. But where is this to be found in the Scriptures? In no part, properly understood. In the new heavens and the new earth none of the wicked shall be found; for therein dwells righteousness - nothing but God and righteous spirits; but at the same time the wicked shall be in their own place. And to suppose that they shall be annihilated, is as great a heresy, though scarcely so absurd, as to believe that the pains of damnation are emendatory, and that hellfire shall burn out. There is presumptive evidence from Scripture to lead us to the conclusion, that if there be not eternal punishment, glory will not be eternal; as the same terms are used to express the duration of both. No human spirit that is not united to God can be saved. Those who are Far from Thee shall perish - they shall be lost, undone, ruined, and that without remedy. Being separated from God by sin, they shall never be rejoined; the great gulf must be between them and their Maker eternally.
All them that go a whoring from thee - That is, all that worship false gods; all idolaters. This is the only meaning of the word in such a connection. I have explained this elsewhere.
