Hebrews 9:26

“For then must he often have suffered since the foundation of the world, etc..] For if it was necessary that he should often offer up himself now, which is the same as to suffer, since the sacrifice of himself, the same was necessary before; seeing sin was in the world from the beginning, and the saints from the foundation of the world had their sins expiated by the sacrifice of Christ; but the truth is, Christ's sufferings were but once, though the virtue of them is always, both before and after; nor can he suffer more, or again, because of his power over death and the grave, and because he has effectually obtained what he suffered for: but now once in the end of the world hath he appeared…”

“then--in that case. must . . . have suffered--rather as Greek, "It would have been necessary for Him often to suffer." In order to "offer" (Heb 9:25), or present Himself often before God in the heavenly holiest place, like the legal high priests making fresh renewals of this high priestly function. He would have had, and would have often to suffer. His oblation of Himself before God was once for all (that is, the bringing in of His blood into the heavenly Holy of Holies), and therefore the preliminary suffering was once for all. since the foundation of the world--The continued sins of men, from their first creation, would entail a continual suffering on earth, and consequent oblation of His…”

“For then must he often have suffered - That is, if his blood had no more efficacy than what the Jewish high priest offered, and which was so often repeated, it would have been necessary that Christ should have often died. But now once - Once for all; once in the sense that it is not to be repeated again - ἅπαξ hapax. In the end of the world - In the last dispensation or economy; that under which the affairs of the world will be wound up; see the phrase fully explained in Hebrews 1:2 note, and Acts 2:17 note; 1 Corinthians 10:11, and Isaiah 2:2. Hath he appeared - He has been manifested in human form. To put away sin - To remove the punishment due to sin, or to provide a way of pardon; and,…”

“For then he must often have suffered from the foundation of the world - This supposes, That by suffering once he atoned for all the sins which had been committed from the foundation of the world. That he could not have atoned for them without suffering. At the consummation of the ages - The sacrifice of Christ divides the whole age or duration of the world into two parts, and extends its virtue backward and forward, from this middle point wherein they meet to abolish both the guilt and power of sin. Hebrews 9:27”

“9:26 If that had been necessary: The author makes an argument using reductio ad absurdum (reduction to absurdity), logically showing that Christ’s one-time sacrifice must be permanently effective. Since Christ himself is the sacrifice as well as the high priest, if his offering were made every year as with the earthly high priests, he would have to die again and again. But of course this is absurd; so, clearly, Christ died once for all time . . . to remove sin.”
