(14) I AM THAT I AM.—It is generally assumed that this is given to Moses as the full name of God. But perhaps it is rather a deep and mysterious statement of His nature. “I am that which I am.” My nature, i.e., cannot be declared in words, cannot be conceived of by human thought. I exist in such sort that my whole inscrutable nature is implied in my existence. I exist, as nothing else does—necessarily, eternally, really. If I am to give myself a name expressive of my nature, so far as language can be, let me be called “I AM.”

Tell them I AM hath sent me unto you.—I AM, assumed as a name, implies (1) an existence different from all other existence. “I am, and there is none beside me” (Isaiah 45:6); (2) an existence out of time, with which time has nothing to do (John 8:58); (3), an existence that is real, all other being shadowy; (4) an independent and unconditioned existence, from which all other is derived, and on which it is dependent.

Exodus 3:14. God said — Two names God would be known by: 1st, A name that speaks what he is in himself, I AM THAT I AM. The Septuagint renders the words ειμι ο ων, I AM the existing Being, or HE WHO IS; and the Chaldee, I AM HE WHO IS, and WHO WILL BE. That is, I am He that enjoys an essential, independent, immutable, and necessary existence, He that IS, and WAS, and IS TO COME. It explains his name Jehovah, and signifies, 1st, That he is self- existent: he has his being of himself, and has no dependance on any other. And being self-existent, he cannot but be self-sufficient, and therefore all-sufficient, and the inexhaustible fountain of being and blessedness. 2d, That he is eternal and unchangeable: the same yesterday, to-day, and for ever. For the words are with equal propriety rendered, I WILL BE WHAT I AM, or, I AM WHAT I WILL BE, or, I WILL BE WHAT I WILL BE. Other beings are, and have been, and shall be; but because what they have been might have been otherwise, and what they are might possibly not have been at all, and what they shall be may be very different from what now is therefore their changeable, dependant, and precarious essence, which to-day may be one thing, to- morrow another thing, and the next day possibly nothing at all, scarce deserves the name of being. There is another consideration which makes this name peculiarly applicable to God, namely that he is the fountain of all being and perfection, and that from him all things have derived their existence; so that it is he alone that has life in himself: and no creature, of whatever rank or order, has so much as an existence of its own: For in him we live, and move, and have our being. And though divers of God’s attributes are, through his goodness, participated by his creatures, yet because they possess them in a way so inferior to that transcendent, peculiar, and divine manner in which they belong to God, the Scriptures seem absolutely to exclude created beings from any title to those attributes.

Thus our Saviour says, There is none good but one, that is God. Thus St. Paul terms God the only Potentate, though the earth be shared by several potentates; and the only wise God, though many men and the holy angels are wise. And thus he describes him as one who only hath immortality, although angels and human souls are also immortal. In so incommunicable a manner does the superiority of God’s nature make him possess those very excellences which the diffusiveness of his goodness has induced him to communicate. 3d, 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.

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.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. 10-22. Come now therefore, and I will send thee—Considering the patriotic views that had formerly animated the breast of Moses, we might have anticipated that no mission could have been more welcome to his heart than to be employed in the national emancipation of Israel. But he evinced great reluctance to it and stated a variety of objections [Ex 3:11, 13; 4:1, 10] all of which were successfully met and removed—and the happy issue of his labors was minutely described. I am that I am; a most comprehensive and significant name, and most proper for the present occasion, It notes,

1. The reality of his being; whereas idols are nothings, 1 Corinthians 8:4, all their divinity is only in the fancies and opinions of men.

2. The necessariness, eternity, and unchangeableness of his being; whereas all other beings once were not, and, if he please, they shall be no more; and all their being was derived from him, and wholly depends upon him; and he only is by and from’ himself.

3. The constancy and certainty of his nature, and will, and word. The sense is, I am the same that ever I was; the same who made the promises to Abraham, &c., and am now come to perform them; who, as I can do what I please, so I will do what I have said. Heb. I shall be what I shall be. He useth the future tense; either,

1. Because that tense in the use of the Hebrew tongue comprehends all times, past, present, and to come, to signify that all times are alike to God, and all are present to him; and therefore what is here, I shall be, is rendered, I am, by Christ, John 8:58. See Psalm 90:4 2 Peter 3:8. Or,

2. To intimate, though darkly, according to that state and age of the church, the mystery of Christ’s incarnation. I shall be what I shall be, i.e. God-man; and I who now come in an invisible, though glorious, manner to deliver you from this temporal bondage, shall in due time come visibly, and by incarnation, to save you and all my people from a far worse slavery and misery, even from your sins, and from wrath to come. Of this name of God, see Revelation 1:4,8 16:5.

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.
