Deuteronomy 9:9-11

9:9 When I went up the mountain to receive the stone tablets, the tablets of the covenant that the Lord made with you, I remained there forty days and nights, eating and drinking nothing. 9:10 The Lord gave me the two stone tablets, written by the very finger of God, and on them was everything he said to you at the mountain from the midst of the fire at the time of that assembly. 9:11 Now at the end of the forty days and nights the Lord presented me with the two stone tablets, the tablets of the covenant.

Deuteronomy 9:15

9:15 So I turned and went down the mountain while it was blazing with fire; the two tablets of the covenant were in my hands.
