2:23 Him, being delivered by the determinate counsel and foreknowledge of God - The apostle here anticipates an objection, Why did God suffer such a person to be so treated? Did he not know what wicked men intended to do? And had he not power to prevent it? Yea. He knew all that those wicked men intended to do. And he had power to blast all their designs in a moment.But he did not exert that power, because he so loved the world!Because it was the determined counsel of his love, to redeem mankind from eternal death, by the death of his only - begotten Son.
2:24 Having loosed the pains of death - The word properly means, the pains of a woman in travail. As it was not possible that he should be held under it - Because the Scripture must needs be fulfilled.
