Many people believe the Israelites were enslaved in Egypt for 400 years based on what is written in Genesis 15:13 or 430 years based on what it says in Exodus 12:40. However, the Israelites couldn’t have been enslaved in Egypt for 400 or 430 years. The issue is that these numbers conflict with the math in the story; in actuality, they couldn’t have been in Egypt for more than 350 years.
