2. If, therefore, in the present time also, God, knowing the number of those who will not believe, since He foreknows all things, has given them over to unbelief, and turned away His face from men of this stamp, leaving them in the darkness which they have themselves chosen for themselves, what is there wonderful if He did also at that time give over to their unbelief, Pharaoh, who never would have believed, along with those who were with him? As the Word spake to Moses from the bush: "And I am sure that the king of Egypt will not let you go, unless by a mighty hand." And for the reason that the Lord spake in parables, and brought blindness upon Israel, that seeing they might not see, since He knew the [spirit of] unbelief in them, for the same reason did He harden Pharaoh's heart; in order that, while seeing that it was the finger of God which led forth the people, he might not believe, but be precipitated into a sea of unbelief, resting in the notion that the exit of these [Israelites] was accomplished by magical power, and that it was not by the operation of God that the Bed Sea afforded a passage to the people, but that this occurred by merely natural causes (sed naturaliter sic se habere).
