Deuteronomy 9:9-11

9This happened when I was on the mountain receiving the tablets of stone inscribed with the words of the covenant that the Lord had made with you. I was there for forty days and forty nights, and all that time I ate no food and drank no water.

10The Lord gave me the two tablets on which God had written with his own finger all the words he had spoken to you from the heart of the fire when you were assembled at the mountain.

11“At the end of the forty days and nights, the Lord handed me the two stone tablets inscribed with the words of the covenant.
