God Almighty - Rather, "El Shaddai," (שׁדי אל 'êl shadday), it is better to keep this as a proper name.

By the name of God Almighty - אל שדי EL-Shaddal, God All-sufficient; God the dispenser or pourer-out of gifts. See Clarke on Genesis 17:1 (note).

But by my name JEHOVAH was I not known to them - This passage has been a sort of crux criticorum, and has been variously explained. It is certain that the name Jehovah was in use long before the days of Abraham, see Genesis 2:4, where the words יהוה אלהים Jehovah Elohim occur, as they do frequently afterwards; and see Genesis 15:2, where Abraham expressly addresses him by the name Adonai Jehovah; and see Genesis 15:7, where God reveals himself to Abraham by this very name: And he said unto him, I am Jehovah, that brought thee out of Ur of the Chaldees. How then can it be said that by his name Jehovah he was not known unto them? Several answers have been given to this question; the following are the chief: - 1. The words should be read interrogatively, for the negative particle לא lo, not, has this power often in Hebrew. "I appeared unto Abraham, Isaac, and Jacob by the name of God Almighty, and by my name Jehovah was I not also made known unto them?" 2. The name Jehovah was not revealed before the time mentioned here, for though it occurs so frequently in the book of Genesis, as that book was written long after the name had come into common use, as a principal characteristic of God, Moses employs it in his history because of this circumstance; so that whenever it appears previously to this, it is by the figure called prolepsis or anticipation. 3. As the name יהוה Jehovah signifies existence, it may be understood in the text in question thus: "I appeared unto Abraham, Isaac, and Jacob by my name God Almighty, or God All-sufficient, i.e., having all power to do all good; in this character I made a covenant with them, supported by great and glorious promises; but as those promises had respect unto their posterity, they could not be fulfilled to those fathers: but now, as Jehovah, I am about to give existence to all those promises relative to your support, deliverance from bondage, and your consequent settlement in the promised land." 4. The words may be considered as used comparatively: though God did appear to those patriarchs as Jehovah, and they acknowledged him by this name, yet it was but comparatively known unto them; they knew nothing of the power and goodness of God, in comparison of what the Israelites were now about to experience.

I believe the simple meaning is this, that though from the beginning the name Jehovah was known as one of the names of the Supreme Being, yet what it really implied they did not know. אל שלי El-Shaddai, God All-sufficient, they knew well by the continual provision he made for them, and the constant protection he afforded them: but the name יהוה Jehovah is particularly to be referred to the accomplishment of promises already made; to the giving them a being, and thus bringing them into existence, which could not have been done in the order of his providence sooner than here specified: this name therefore in its power and significancy was not known unto them; nor fully known unto their descendants till the deliverance from Egypt and the settlement in the promised land. It is surely possible for a man to bear the name of a certain office or dignity before he fulfills any of its functions. King, mayor, alderman, magistrate, constable, may be borne by the several persons to whom they legally belong, before any of the acts peculiar to those offices are performed. The King, acknowledged as such on his coronation, is known to be such by his legislative acts; the civil magistrate, by his distribution of justice, and issuing warrants for the apprehending of culprits; and the constable, by executing those warrants. All these were known to have their respective names, but the exercise of their powers alone shows what is implied in being king, magistrate, and constable. The following is a case in point, which fell within my own knowledge.

A case of dispute between certain litigious neighbors being heard in court before a weekly sitting of the magistrates, a woman who came as an evidence in behalf of her bad neighbor, finding the magistrates inclining to give judgment against her mischievous companion, took her by the arm and said, "Come away! I told you you would get neither law nor justice in this place." A magistrate, who was as much an honor to his function as he was to human nature, immediately said, "Here, constable! take that woman and lodge her in Bridewell, that she may know there is some law and justice in this place." Thus the worthy magistrate proved he had the power implied in the name by executing the duties of his office. And God who was known as Jehovah, the being who makes and gives effect to promises, was known to the descendants of the twelve tribes to be That Jehovah, by giving effect and being to the promises which he had made to their fathers.

And I appeared unto Abraham, unto Isaac, and unto Jacob, by the name of God Almighty,.... Able to fulfil all his purposes, promises, and covenant, with whom nothing is impossible; or Elshaddai, God all-sufficient, who has a sufficiency of happiness in himself, and everything to supply the wants of his creatures in things temporal and spiritual, see Genesis 17:1,

but by my name Jehovah was I not known to them; which he had in the preceding verse called himself by. This is not to be understood absolutely; for it is certain that he had made himself known by this name, and this name was known unto Abraham, Isaac, and Jacob, Genesis 15:6, and but comparatively, as some think; that is, he was not so much made known to them by the one name as the other; though it may be questioned whether the one was more used in speaking to them than the other; wherefore others think, as Saadiah Gaon, that the word only is to be supplied, as in Genesis 32:28 and the sense to be, that by his name Jehovah he was not only made known to them, but by his name Elshaddai, and others also; and others reconcile the difficulty thus, that though the name Jehovah itself was known to the patriarchs, by which they were assured that God is eternal, immutable, and faithful to his promises; yet he was not known as to the efficacy of this name, or with respect to the actual performance of his promise, as he now would be by delivering the children of Israel out of Egypt, and bringing them into the land of Canaan; though perhaps, by reading the words with an interrogation, the clause will appear more plain, "and by my name Jehovah was I not known to them?" (t) verily I was. Josephus (u) says, this name was not before made known to men, and that it was not lawful for a man to speak it; and this is the common notion of the Jews, that it is ineffable, and not lawful to be pronounced, and therefore they put Adonai and Elohim in the room of it, and the vowel points of these words to it, which is a false and superstitious notion: this name was known among the Heathens; it is the same with in the oracle of Apollo (w); and Diodorus Siculus (x) says, that with the Jews Moses is said to give laws from a God called "IAO", and is the same which in Philo Byblius (y) is called Jevo; and both are no other than a corruption of Jah or Jehovah; and perhaps the of the Pythagoreans (z), by which they swore, is the same with the tetragrammaton, or this word of four letters, with the Jews.

(a) By which he signifies that he will perform indeed that which he promised to their fathers: for this name declares that he is constant and will perform his promise.

3. I . God Almighty-All enemies must fall, all difficulties must vanish before My omnipotent power, and the patriarchs had abundant proofs of this.

but by my name, &c.-rather, interrogatively, by My name Jehovah was I not known to them? Am not I, the Almighty God, who pledged My honor for the fulfilment of the covenant, also the self-existent God who lives to accomplish it? Rest assured, therefore, that I shall bring it to pass. This passage has occasioned much discussion; and it has been thought by many to intimate that as the name Jehovah was not known to the patriarchs, at least in the full bearing or practical experience of it, the honor of the disclosure was reserved to Moses, who was the first sent with a message in the name of Jehovah, and enabled to attest it by a series of public miracles.

6:1-9 We are most likely to prosper in attempts to glorify God, and to be useful to men, when we learn by experience that we can do nothing of ourselves; when our whole dependence is placed on him, and our only expectation is from him. Moses had been expecting what God would do; but now he shall see what he will do. God would now be known by his name Jehovah, that is, a God performing what he had promised, and finishing his own work. God intended their happiness: I will take you to me for a people, a peculiar people, and I will be to you a God. More than this we need not ask, we cannot have, to make us happy. He intended his own glory: Ye shall know that I am the Lord. These good words, and comfortable words, should have revived the drooping Israelites, and have made them forget their misery; but they were so taken up with their troubles, that they did not heed God's promises. By indulging discontent and fretfulness, we deprive ourselves of the comfort we might have, both from God's word and from his providence, and go comfortless.
