Exodus 32:8

They have turned aside quickly out of the way which I commanded them, their guilt was increased by the great hurry which they displayed in choosing the ways of idolatry; they have made them a molten calf, and have worshiped it, and have sacrificed thereunto, and said, These be thy gods, O Israel, which have brought thee up out of the land of Egypt. With the children of Israel engaged in wilful idolatry, it was impossible for the work on the mountain to continue, and the indignation of the Lord breaks forth like a flood.
