Exodus 6:3

And I appeared to Abraam and Isaac and Jacob, being their God, but I did not manifest to them my name Lord.

And I appeared unto Abraham, unto Isaac, and unto Jacob, by the name of God Almighty, but by my name Jehovah was I not known to them.

I appeared to Abraham, to Isaac, and to Jacob, as God Almighty; but by my name Yahweh I was not known to them.
