1. Then Hashem said unto Moshe, Now shalt thou see what I will do to Pharaoh; for through a yad chazakah shall he let them go, and with a yad chazakah shall he drive them out of his land.
2. And Elohim spoke unto Moshe, and said unto him, I am Hashem;
3. And I appeared unto Avraham, unto Yitzchak, and unto Ya'akov, as El Shaddai, but by My Shem Hashem I did not make Myself known to them.
