Deuteronomy 9:9-10

When I went up into the mountain to receive the tablets of stone, the tablets of the covenant which the LORD made with you, then I stayed on the mountain forty days and forty nights. I neither ate bread nor drank water. Then the LORD delivered to me two tablets of stone written with the finger of God, and on them were all the words which the LORD had spoken to you on the mountain from the midst of the fire in the day of the assembly.
