In this Torah portion, Moses stays with G-d on Mount Sinai for 40 days and 40 nights. There, he is given the 10 Commandments on stone tablets. Fearing Moses will never return, the Israelites turn to Aaron, who demands that everyone bring him their gold, so he can make a golden calf. When Moses comes down the mountain and sees the people dancing around this idol, he smashes the tablets on the ground. G-d punishes with a plague all the Israelites who were involved. Moses builds a tent to be his meeting place with G-d.
