Here are the facts as related in the book of Exodus

The commandments on the previous page were recited by Moses who conviced his people that they had come from the Lord; they were never written. Moses was the only human that read the commandments on the stone tablets that were given him by the Lord. For some inexplicable reason, he broke the tablets before anyone else had an opportunity to read them (Exodus 32:19). He never told the people what was written on the tablets and allowed them to believe that the commandments listed on the previous page and in Exodus Chap. 20 were the ones written on the stone tablets that he broke; this may be hard to believe until you read Exodus Chapter 34. In Exodus 34:1, the Lord said to Moses: "Cut two tables of stone like the first and I will write upon the tables the words that were on the first tables that you broke." What was written is told in Exodus 34:14-26 and can be seen on the next page. Although the re-written commandments were identical to the ones on the tablets that Moses broke, most of them are not even similar to the ones that Moses had recited to his people. In Exodus 34:28, it is written: "And he was there with the Lord forty days and forty nights; he did neither eat bread, nor drink water. And he wrote upon the tables the word of the covenant, the ten commandments."
(Of course Moses didn't eat bread or drink water; the lord had prepared a sumptuous feast for him every day with vintage wines instead of water. You didn't really think that the lord would let Moses die of thirst before he took the tablets down the mountain did you. In fact, he drank so much wine that his face looked like Rudolph's nose by the time he got to the bottom. If he hadn't been so hung over, he probably wouldn't have tripped on a rock and broken the the first set of tablets.)
