Shemot 32:7-8

And HASHEM said unto Moshe, Go, get thee down; for thy people, which thou broughtest out of Eretz Mitzrayim, have corrupted themselves; They have turned aside quickly from HaDerech which I commanded them; they have made them an Egel Masekhah, and have bowed down to it, and have sacrificed thereunto, and said, These be thy elohim, O Yisroel, which have brought thee up out of the Eretz Mitzrayim.
