How it works
The Bible tells how the people of Israel left Egypt, where they had been slaves, and walked through the wilderness to a huge mountain called Sinai.
On the third morning there was thunder, lightning, a thick cloud and a loud trumpet. Moses went up into the cloud, and the people heard ten rules.
The first four rules are about loving God, and the last six are about loving people. Moses told the people all the words and wrote them in a book.
Moses went up the mountain again and stayed for forty days and forty nights. At the end he was given two stone tablets with the ten rules on them.
