Some commentators believe God was angry at Moses for breaking those tablets with the 10 Commandments, but I don’t believe so. When Moses broke the tablets, Moses was simply acknowledging the fact that the people had already broken the covenant that just 40 days earlier they had promised to uphold when they said, “What you say, we will do.” So it was appropriate for Moses to break those tablets. But it was also appropriate that the tablets had to be remade.
Moses had a friendship with God that His contemporaries did not have. Paul says that thanks to Yeshua, we can approach God without a veil.
