Deuteronomy 9:9-12

9when I went up the mountain to receive the tables of stone, the tables of the covenant which Jehovah made with you, and I abode in the mountain forty days and forty nights, — I ate no bread and drank no water, —

10— and Jehovah delivered to me the two tables of stone written with the finger of 1God; and on them [was written] according to all the words which Jehovah spoke with you on the mountain from the midst of the fire on the day of the assembly.

11And it came to pass at the end of forty days and forty nights, that Jehovah gave me the two tables of stone, the tables of the covenant.

12And Jehovah said unto me, Arise, go down quickly from hence; for thy people which thou hast brought forth out of Egypt have corrupted themselves; they have quickly turned aside from the way which I commanded them: they have made for themselves a molten image.
