Deuteronomy 9:9-12

9I climbed the mountain to meet with the Lord. I received the two flat stones with the covenant that he had made with you. I stayed there for 40 days and nights. During that time, I did not eat or drink anything.

10Then the Lord gave the two flat stones to me. He had written all his commands on the stones with his own finger. The Lord spoke those commands to you from middle of the fire. That was on the day when you all came together at the mountain.

11After those 40 days and nights, the Lord gave me the two flat stones. They had his covenant on them.

12Then the Lord said to me, ‘Now go down the mountain! The people that you led out of Egypt have done something very bad. They have already refused to obey my commands. They have used gold to make an idol for themselves.’
