Exodus 6:3 KJV

1Then the LORD said unto Moses, Now shalt thou see what I will do to Pharaoh: for with a strong hand shall he let them go, and with a strong hand shall he drive them out of his land.

2And God spake unto Moses, and said unto him, I am the LORD:

3And 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.

4And I have also established my covenant with them, to give them the land of Canaan, the land of their pilgrimage, wherein they were strangers.

5And I have also heard the groaning of the children of Israel, whom the Egyptians keep in bondage; and I have remembered my covenant.
