“And God said moreover unto Moses, Thus shalt thou say unto the children of Israel, The LORD God of your fathers, the God of Abraham, the God of Isaac, and the God of Jacob, hath sent me unto you: this is my name for ever, and this is my memorial unto all generations.”
King James Version (KJV)
3:15 The Lord God of our fathers hath sent me unto you - Thus God made himself known, that he might revive among them the religion of their fathers, which was much decayed, and almost lost. And that he might raise their expectations of the speedy performance of the promises made unto their fathers: Abraham, Isaac, and Jacob are particularly named, because with Abraham the covenant was first made, and with Isaac and Jacob oft expressly renewed, and these three were distinguished from their brethren, and chosen to be the trustees of the covenant. This God will have to be his name for ever, and it has been, is, and will be his name, by which his worshippers know him, and distinguish him from all false gods.
