Moreover he said,
I am the God of your father, the God of Abraham, the God of Isaac, and
the God of Jacob.
And Moses hid his face; for he was afraid to look upon God.

Aphrahat the Persian Sage
And when the holy One called Moses from the bush he said thus to him: “I am the God of Abraham, of Isaac and of Jacob.” When Death heard this utterance, he trembled and feared and was terrified and perturbed and knew that he had not become king forever over the children of Adam. From the hour that he heard God saying to Moses, “I am the God of Abraham, of Isaac and of Jacob,” Death [struck] his hands together, for he learned that God is king of the dead and of the living and that it is appointed to the children of Adam to come forth from his darkness and arise with their bodies. And observe that our Redeemer Jesus also, when he repeated this utterance to the Sadducees, when they were disputing with him about the resurrection of the dead, thus said, “God is not [God] of the dead, for all are alive unto him.”
For the name of Divinity is given for the highest honor in the world, and with whomsoever God is well pleased, he applies it to him. But however, the names of God are many and are venerable, as he delivered his names to Moses, saying to him, “I am the God of your fathers, the God of Abraham and the God of Isaac and the God of Jacob. This is my name forever, and this is my memorial unto generations.” And he called his name “Ahiyah ashar Ahiyah,”“El Shaddai” and “Adonai Sabaoth.” By these names God is called. The great and honorable name of Godhead he withheld not from his righteous ones; even as, though he is the great king, without grudging he applied the great and honorable name of kingship to men who are his creatures.
God gives witness and says, “I am the God of Abraham, the God of Isaac and the God of Jacob.” Were there not other patriarchs? Was not Noah a holy man before these, who alone in the whole human race together with his whole house deserved to be delivered from the flood, in whom and in his sons the church is represented? They escape the flood, with wood carrying them. And then afterwards [come] the great men whom we know, whom Holy Scripture commends, Moses faithful in all his house. And those three are named, as if they alone were deserving of him: “I am the God of Abraham, the God of Isaac and the God of Jacob; this is my name forever.” An enormous mystery! The Lord has the power to open both our mouths and your hearts that we may be able to speak as he has deigned to reveal and that you may be able to grasp as it is advantageous to you. Therefore those patriarchs are three: Abraham, Isaac and Jacob. You already know that the sons of Jacob were twelve and from them are the people of Is...
But the Savior also demonstrated the great ignorance of the Sadducees by bringing forward their own hierophant Moses, who was well and clearly acquainted with the resurrection of the dead. For he has set before us God, he says, as saying in the bush, “I am the God of Abraham, and the God of Isaac and the God of Jacob.” But of whom is he God, if, according to their argument, these have ceased to live? For he is the God of the living; and therefore certainly and altogether they will rise, when his almighty right hand brings them thereunto; and not them only but also all who are upon the earth.
Hid, out of respect, and perhaps fearing lest he should die, Genesis xvi. 13. (Calmet)
God takes the title of these three patriarchs, because he had promised Chanaan to each of them, and because they were eminent for virtue. God is repeated thrice, to insinuate the mystery of the blessed Trinity, and to show that the Lord watches over each individual, as if that one alone existed. (Menochius)
Of the other titles, some are evidently names of his authority, others of his government of the world, and of this viewed under a twofold aspect: the one before, the other in, the incarnation. For instance, the Almighty, the King of Glory, or of the Ages, or of the Powers, or of the Beloved or of Kings. Or again, the Lord of Sabaoth, that is, of hosts, or of powers or of lords; these are clearly titles belonging to his authority. But the God either of salvation or of vengeance, or of peace, or of righteousness, or of Abraham, Isaac and Jacob, and of all the spiritual Israel that sees God—these belong to his government. For since we are governed by these three things, the fear of punishment, the hope of salvation and of glory besides, and the practice of the virtues by which these are attained, the name of the God of vengeance governs fear, and that of the God of salvation our hope, and that of the God of virtues our practice; that whoever attains to any of these may, as carrying God in...
