I am that I am - That is, "I am what I am." The words express absolute, and therefore unchanging and eternal Being. The name, which Moses was thus commissioned to use, was at once new and old; old in its connection with previous revelations; new in its full interpretation, and in its bearing upon the covenant of which Moses was the destined mediator.

I am that I am - אהיה אשר אהיה Eheyeh asher Eheyeh. These words have been variously understood. The Vulgate translates Ego Sum Qui Sum, I am who am. The Septuagint, Εγω ειμι ὁ Ων, I am he who exists. The Syriac, the Persic, and the Chaldee preserve the original words without any gloss. The Arabic paraphrases them, The Eternal, who passes not away; which is the same interpretation given by Abul Farajius, who also preserves the original words, and gives the above as their interpretation. The Targum of Jonathan, and the Jerusalem Targum paraphrase the words thus: "He who spake, and the world was; who spake, and all things existed." As the original words literally signify, I will be what I will be, some have supposed that God simply designed to inform Moses, that what he had been to his fathers Abraham, Isaac, and Jacob, he would be to him and the Israelites; and that he would perform the promises he had made to his fathers, by giving their descendants the promised land. It is difficult to put a meaning on the words; they seem intended to point out the eternity and self-existence of God. Plato, in his Parmenides, where he treats sublimely of the nature of God, says, Ουδ' αρα ονομα εστιν αυτῳ, nothing can express his nature; therefore no name can be attributed to him. See the conclusion of this chapter, Exodus 3:22 (note) and on the word Jehovah, Exodus 34:6 (note), Exodus 34:7 (note).

And God said unto Moses, I am that I am,.... This signifies the real being of God, his self-existence, and that he is the Being of beings; as also it denotes his eternity and immutability, and his constancy and faithfulness in fulfilling his promises, for it includes all time, past, present, and to come; and the sense is, not only I am what I am at present, but I am what I have been, and I am what I shall be, and shall be what I am. The Platonists and Pythagoreans seem to have borrowed their from hence, which expresses with them the eternal and invariable Being; and so the Septuagint version here is : it is said (z), that the temple of Minerva at Sais, a city of Egypt, had this inscription on it,"I am all that exists, is, and shall be.''And on the temple of Apollo at Delphos was written the contraction of "I am" (a). Our Lord seems to refer to this name, John 8:58, and indeed is the person that now appeared; and the words may be rendered, "I shall be what I shall be" (b) the incarnate God, God manifest in the flesh:

thus shalt thou say unto the children of Israel, I AM hath sent me unto you; or as the Targum of Jonathan has it,"I am he that is, and that shall be.''This is the name Ehjeh, or Jehovah, Moses is empowered to make use of, and to declare, as the name of the Great God by whom he was sent; and which might serve both to encourage him, and strengthen the faith of the Israelites, that they should be delivered by him.

(z) Phutarch. de Iside & Osir. (a) Plato in Timaeo. (b) "ero qui ero", Pagninus, Montanus, Fagius, Vatablus.

And God said unto Moses, I {n} AM THAT I AM: and he said, Thus shalt thou say unto the children of Israel, I AM hath sent me unto you.

(n) The God who has always been, am, and shall be: the God almighty, by whom all things have their being, and the God of mercy, mindful of my promise.

3:14 And God said - Two names God would now be known by. A name that speaks what he is in himself, I am that I am - This explains his name Jehovah, and signifies, 1st, That he is self - existent; he has his being of himself, and has no dependence upon any other. And being self - existent he cannot but be self - sufficient, and therefore all - sufficient, and the inexhaustible fountain of being and bliss. 2dly, That he is eternal and unchangeable, always the same, yesterday to - day, and for ever: he will be what he will be, and what he is. 3dly. That he is faithful and true to all his promises, unchangeable in his word as well as in his nature, and not a man that he should lie. Let Israel know this, I am hath sent me unto you. A name that speaks what he is to his people. Lest that name I am should puzzle them, he is farther directed to make use of another name of God, more familiar.

3:11-15 Formerly Moses thought himself able to deliver Israel, and set himself to the work too hastily. Now, when the fittest person on earth for it, he knows his own weakness. This was the effect of more knowledge of God and of himself. Formerly, self-confidence mingled with strong faith and great zeal, now sinful distrust of God crept in under the garb of humility; so defective are the strongest graces and the best duties of the most eminent saints. But all objections are answered in, Certainly I will be with thee. That is enough. Two names God would now be known by. A name that denotes what he is in himself, I AM THAT I AM. This explains his name Jehovah, and signifies, 1. That he is self-existent: he has his being of himself. 2. That he is eternal and unchangeable, and always the same, yesterday, to-day, and for ever. 3. That he is incomprehensible; we cannot by searching find him out: this name checks all bold and curious inquiries concerning God. 4. That he is faithful and true to all his promises, unchangeable in his word as well as in his nature; let Israel know this, I AM hath sent me unto you. I am, and there is none else besides me. All else have their being from God, and are wholly dependent upon him. Also, here is a name that denotes what God is to his people. The Lord God of your fathers sent me unto you. Moses must revive among them the religion of their fathers, which was almost lost; and then they might expect the speedy performance of the promises made unto their fathers.
