Then the LORD spoke to Moses. He said, "Now you will see what I will do to Pharaoh. Because of my powerful hand, he will let the people of Israel go. Because of my mighty hand, he will drive them out of his country."
God continued, "I am the Lord.
I appeared to Abraham, Isaac and Jacob as the Mighty God. But I did not show them the full meaning of my name, The Lord.
"I also made my covenant with them. I promised to give them the land of Canaan. That is where they lived as outsiders.
Also, I have heard the groans of the Israelites. The Egyptians are keeping them as slaves. But I have remembered my covenant.
"So tell the people of Israel, 'I am the Lord. I will throw off the heavy load the Egyptians have put on your shoulders. I will set you free from being slaves to them. I will reach out my arm and save you with mighty acts when I judge Egypt.
