This is the Moses who was with the gathering of the Israelites in the desert. He was with the angel that spoke to him at Mount Sinai, and he was with our ancestors. He received commands from God that give life, and he gave those commands to us.
So what was the law for? It was given to show that the wrong things people do are against God’s will. And it continued until the special descendant, who had been promised, came. The law was given through angels who used Moses for a mediator to give the law to people.
He said: “The Lord came from Mount Sinai and rose like the sun from Edom; he showed his greatness from Mount Paran. He came with thousands of angels from the southern mountains.
