Exodus 6:2-5 New King James Version (NKJV)

2. And God spoke to Moses and said to him: “I am the Lord.

3. I appeared to Abraham, to Isaac, and to Jacob, as God Almighty, but by My name Lord I was not known to them.

4. I have also established My covenant with them, to give them the land of Canaan, the land of their pilgrimage, in which they were strangers.

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