So it should come as no surprise that the ancient Egyptians would not have wanted to record or even remember what was perhaps their greatest humiliation—the national devastation that occurred when their Israelite slaves won their freedom and Egypt’s might proved powerless to stop them. This attitude is not limited to the past. Even today, some of what went on during the two world wars is still hotly debated by historians on both sides of the issue.
It seems too much to hope for, then, that a proud and powerful nation such as Egypt, whose rulers were considered gods, would record that their mighty army was ignominiously crushed by a band of virtually unarmed slaves who had a more powerful deity on their side. This would have embarrassed them in front of the entire known world. It’s more natural to believe they simply licked their wounds and tried to cover up all traces of this humiliating national episode, especially since they are known to have done this on other occasions.
