3.בני ישראל were acting like stiff necks (stubbern) so ה wants to destroy them because they did a חת העגל but משׁה trys to convince ה that he shouldn't because he promised אברהם, יצחק, ,ויעקב.
ה tells משׁה to go, go down רשׁי''י asks why does it say go, go down why cant it say go down or go. He answers the first go means משׁה will go down with greatness and that he should go down the mountain. so he goes down and he sees them dancing around the golden cow. he also sees יהודה saying that there is a war coming but then משׁה said its not the sound of war its the sound of pain. so then משׁה took the cow and throws it into a fire then takes the ashes throws it into water and he made בני ישרא drink it.
משׁה went back to get the לוחת and משׁהsays if ה doesnt forgive them then he should earase him from the תורה so ה says instead he will earase anyone from the תורה that sined.
