Exodus 14:13b (NIV)  The Egyptians you see today you will never see again.

Excerpt:

Unwelcomed memories tend to blind-side us. They show up in routine activities like driving, taking a shower, and washing dishes. All of a sudden out of what appears to be nowhere comes the rush of a painful memory of the past. A dark foreboding feeling often accompanies the unwelcomed intruder. Its presence is like that of a demon that comes to torment the Christian believer. This presence can linger for moments, minutes, hours and days. It can be the cause of a sinister depression and even suicide.
