Deuteronomy 9:7-11

Remember, do not forget how you provoked the Lord your God to anger in the wilderness; from the day that you left the land of Egypt until you arrived at this place, you have been rebellious against the Lord.

Even at Horeb you provoked the Lord to anger, and the Lord was so angry with you that He would have destroyed you.

When I went up to the mountain to receive the tablets of stone, the tablets of the covenant which the Lord made with you, then I remained on the mountain for forty days and nights; I neither ate bread nor drank water.

The Lord gave me the two tablets of stone written by the finger of God; and on them were all the words which the Lord had spoken with you at the mountain from the midst of the fire on the day of the assembly.

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