Summary: The Israelites follow what the bible says to do. The main guidelines they go by is the 10 Commandments given by God to them in Exodus chapter 20. They had just came out of Egypt and didn't know what to do so God gave them commandments to follow. Moses was the leader at the time so he and the elders of Israel enforced those commandments. If any commandment was broken then there was judgements or punishments.
Legacy: The Israelites are still alive today and are scattered all over the world. They continue to keep the 10 commandments to the best of their ability during this time. They believe that if they keep the commandments now they will make it to heaven.
