The Sin of the Golden Calf

32:1 When the people saw that Moses delayed in coming down from the mountain, they gathered around Aaron and said to him, “Get up, make us gods that will go before us. As for this fellow Moses, the man who brought us up from the land of Egypt, we do not know what has become of him!”

34:10 He said, “See, I am going to make a covenant before all your people. I will do wonders such as have not been done in all the earth, nor in any nation. All the people among whom you live will see the work of the Lord, for it is a fearful thing that I am doing with you.
