"When the people saw that Moses was so long in coming down from the mountain, they gathered around Aaron and said, "Come, make us gods who will go before us. As for this fellow Moses who brought us up out of Egypt, we don't know what has happened to him."
"Then the LORD said to Moses, "Go down, because your people, whom you brought up out of Egypt, have become corrupt. They have been quick to turn away from what I commanded them and have made themselves an idol cast in the shape of a calf. They have bowed down to it and sacrificed to it and have said, 'These are your gods, O Israel, who brought you up out of Egypt.'
"I have seen these people," the LORD said to Moses, "and they are a stiff-necked people. Now leave me alone so that my anger may burn against them and that I may destroy them. Then I will make you into a great nation.""--Exodus 32:1, 7-10 (Emphasis mine)
