Deuteronomy 9:9-10
Deuteronomy 9:9-10 ASV
When I was gone up into the mount to receive the tables of stone, even the tables of the covenant which Jehovah made with you, then I abode in the mount forty days and forty nights; I did neither eat bread nor drink water. And Jehovah delivered unto me the two tables of stone written with the finger of God; and on them was written according to all the words, which Jehovah spake with you in the mount out of the midst of the fire in the day of the assembly.
