Deuteronomy 9:9-11

Amplified Bible

⁹ 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. ¹⁰ 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. ¹¹ It came about at the end of forty days and forty nights that the Lord gave me the two tablets of stone, the tablets of the covenant.
