Deuteronomy 9:10-11

10 And the Lord gave me the two stone tablets written with the finger of God; on them were all the words that the Lord had spoken to you at the mountain out of the fire on the day of the assembly.
11 At the end of forty days and forty nights the Lord gave me the two stone tablets, the tablets of the covenant.
