Exodus 6:3

“And I appeared unto Abraham, unto Isaac, and unto Jacob, by [the name] of God Almighty, etc.] Able to fulfil all his purposes, promises, and covenant, with whom nothing is impossible; or Elshaddai, God allsufficient, who has a sufficiency of happiness in himself, and everything to supply the wants of his creatures in things temporal and spiritual, (see <011701> 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, (<011506>Genesis 15:6-8 26:2,24 28:13), and but…”

“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?

“God Almighty: El shadday, God Almighty; for shadday is evidently of affinity with the Arabic shadid, strong, mighty, and shiddat, strength, might; so the LXX in Job render it παντοκρατωρ, Vulgate, in Pentateuch, Omnipotens, and Syriac, in Job, chasino. Gen 17:1, Gen 28:3, Gen 35:11, Gen 48:3 but by my name: If Abraham, Isaac, and Jacob, did not know the name Jehovah, then Moses must have used it in Genesis by prolepsis, or anticipation. Mr. Locke and others read it interrogatively, for the negative particle, lo, not, has frequently this power 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?"…”
