Where were the Israelites headed when they left Sinai?
When they left Sinai, the Israelites were headed due north toward the promised land, described as the land of milk and honey. They moved after the tabernacle was completed, preparing to go in and occupy that land under God's direction.
Les explains that after Sinai the Israelites were headed for the promised land. They would head due north, ready to go in and occupy the land of milk and honey. The tabernacle was not going to stand there very long before God said it was time to move on, and move they did. As the book of Exodus closes, the tabernacle is complete and they are going.
