LOL! That was from the Victor Mature movie. I always thought the same thing (because movies of yore were like the Internet of today -- 'they wouldn't steer me wrong'). You actually read the book of Judges and the last you read of Delilah is when she betrayed Samson to the Philistines.
Redemption is always possible (Thank God!), but there is no record of it for Delilah.
Ah, I will not use Hollywood or movies as a point of reference. I could have sworn that she had saved herself, but oddly, it didn’t happen. I wonder what did happen to Delilah in the end, I should research that.
