Gather your wives jewelry and your children jewelry.
3. Hashem talks to Moshe
When the nation counted wrong and did not know what happened to Moshe, they congregated around Aharon and asked him to make them a new god.
4. Moshe comes down the mountain
Aharon told the men to gather their wive's and children's jewelry, but the women and children refused to give it so the men brought their own. Aharon tried to delay creating their new god and told them they will celebrate tomorrow.
5. B'nei Yisroel get punished
" Me L Hashem Ali"
Hashem informs Moshe about B'nei Yisroel's behaviors and tells him to go down the mountain and down from his greatness, because he is only great because of B'nei Yisroel. Moshe davens to Hashem to please not destroy the entire nation.
6. Moshe goes back up the mountain
I will go up the mountain and try to ask for forgives.
Yehoshua was waiting for Moshe at the bottom of the mountain. As they were walking back to the camp, they heard shouts coming from the camp. Yehoshua said it sounded like war, but Moshe said it was not war but rather sounds of weakness. When Moshe saw the egel, he dropped the luchos from his hands.
Moshe burned the calf, grind it and gave it to B'nei Yisroel to drink. He also called out "Me L'Hashem Ali" and all of shevet Levi came to help him kill out the people involved in the sin. Levi killed out 3,000 men. Hashem also brought a plaque on the nation.
Moshe told B'nei Yisroel he was going to go up back to Hashem to ask for forgiveness. Moshe told Hashem to please erase his name from the Torah if he doesn't forgive B'nei Yisroel, so that nobody will say Moshe wasn't worthy of getting B'nei Yisroel forgiven. Hashem told Moshe he will punish the nation with a little bit of the sin of the egel every time he judges them.
