What important event occurred during the hebrews exodus from egypt?

According to the Book of Exodus, Moses received the Ten Commandments during the Exodus from Egypt. At Mount Sinai, the Hebrew people built the golden calf, the people rebelled against Moses. However, this was overcome and the people accepted their chosen-ness and became loyal to God. The Chosen People were led by fire at night and a cloud by day, receiving Manna from heaven every day (except the Sabbath). Eventually, Moses struck a rock twice when God had said to speak to the rock to issue water. This failure to follow instructions led to God denying Moses' arrival to the Promised Land.
