And I appeared unto Abraham, unto Isaac, and unto Jacob, by the name of God Almighty, but by my name the LORD was I not known to them.
All Commentaries on Exodus 6:3 Go To Exodus 6
Eusebius of Caesarea
AD 339
It will naturally be asked how he that is beyond the universe, himself the only almighty God, appeared to the fathers. And the answer will be found if we realize the accuracy of Holy Scripture. For the Septuagint rendering, “I was seen of Abraham, Isaac and Jacob, being their God,” Aquila says, “And I was seen by Abraham, Isaac and Jacob as a sufficient God,” clearly showing that the almighty God himself, who is one, was not seen in his own person and that he did not give answers to the fathers, as he did to Moses by an angel, or a fire or a bush, but “as a sufficient God.” Thus the Father was seen by the fathers through the Son, according to his saying in the Gospels, “He that has seen me has seen the Father.” For the knowledge of the Father was revealed in him and by him. But in cases when he appeared to save men, he was seen in the human form of the Son, giving an earnest before the time to the godly of that salvation which should come through him to all men. But when he was going to be the avenger and chastiser of the wicked Egyptians, he appeared no longer as a sufficient God but as an angel ministering punishment, and in form of fire and flame, ready at once to devour them like wild and thorny undergrowth. So they say that the bush darkly refers to the wild, savage and cruel character of the Egyptians and the fire to the avenging power of the chastisement that overtook them. .
