Deuteronomy 9:9-10
Deuteronomy 9:9-10 AMP
When I went up the mountain to receive the tablets of stone, the tablets of the covenant which the LORD made with you, I remained on the mountain forty days and forty nights; I did not eat food or drink water. The LORD gave me the two tablets of stone written with the finger of God; and on them were written all the words which the LORD had spoken to you at the mountain from the midst of the fire on the day of the assembly.
