This video explains how long the Israelites were in Egypt. Most people believe that they were in Egypt for 430 years. But based on the evidence shown, the Israelites were actually in Egypt for only 215 years.
Subsequently, one may also ask, how long did it take for the Israelites to get to the promised land?
Remember, God's original plan for Israel was to take their Promised Land in days, not decades. It took Israel 40 years to be ready. If you have faith, I believe you can move mountains (even those achieving this year's goals) in just 40 days. Think of the next 40 days as your wilderness.
How long did Moses spend in the wilderness?
After the Ten Plagues, Moses led the Exodus of the Israelites out of Egypt and across the Red Sea, after which they based themselves at Mount Sinai, where Moses received the Ten Commandments. After 40 years of wandering in the desert, Moses died within sight of the Promised Land on Mount Nebo.
Why did they wander for 40 years?
Moses told the Israelites that they were not worthy to inherit the land, and would wander the wilderness for forty years until the generation who had refused to enter Canaan had died, so that it would be their children who would possess the land.
