Exodus 32:15-16, 19-20

Moses turned around and came down from the mountain, carrying the two tablets of The Testimony. The tablets were written on both sides, front and back. God made the tablets and God wrote the tablets—engraved them.

And that’s what it was. When Moses came near to the camp and saw the calf and the people dancing, his anger flared. He threw down the tablets and smashed them to pieces at the foot of the mountain. He took the calf that they had made, melted it down with fire, pulverized it to powder, then scattered it on the water and made the Israelites drink it.
