John Calvin Commentary Hebrews 11:19

"accounting that God [is] able to raise up, even from the dead; from whence he did also in a figure receive him back." — Hebrews 11:19 (ASV)

From whence also, etc. As though he said, “Nor did hope disappoint Abraham, for it was a sort of resurrection, when his son was so suddenly delivered from the midst of death. The word figure, which is here used, is variously explained. I take it simply as meaning likeness; for though Isaac did not really rise from the dead, yet he seemed to have in a manner risen, when he was suddenly and wonderfully rescued through the unexpected favor of God.

However, I do not dislike what some say, who think that our flesh, which is subject to death, is set forth in the ram which was substituted for Isaac. I also grant as true what some have taught, that this sacrifice was a representation of Christ. But I have now to state what the Apostle meant, not what may in truth be said; and the real meaning here, as I think, is, that Abraham did not receive his Son otherwise than if he had been restored from death to new life.
