Then God sent 10 plagues to Egypt. The plagues did not change Ramses ll mind to let the Hebrews go until the last one, were the first born Egyptians life were taken. Ramses let the Hebrews go. So the Hebrews were free.
Ramses changed his mind and told his soldiers to bring them back. Then when Moses saw them come, god told him to do something so the could go through the Red sea. When Moses and his people got to the other side, the Egyptian soldiers drowned.
God gave Moses the Ten Commandments for the Israelites to follow.
