Seriously, we're they just dumb or what?

So I am reading about Samson and Delilah this week (Judges 16). As I read it I just can't keep from thinking, how stupid were these two? Delilah agrees to try to get Samson's secret of his strength out of him to tell the Philistines for money. So she asks him and he lies to her and tells her if anyone ties him with seven fresh thongs (not sure what these are) he will become as weak as any other man. So when he falls asleep she ties him with 7 fresh thongs and then has men hiding in the room. Delilah wakes Samson saying, "Samson, the Philistines are upon you!". He snaps the thongs like threads and the men scurry away.

So I'm thinking, Samson has to be on to her little scheme right? She tries this two more times and two more times he lies to her. He's toying with her. She wakes him up tied with new ropes and with his hair woven into fabric on a loom yelling "Samson, the Philistines are upon you!" two more times. He breaks free easily two more times. So Samson, why didn't you just drop this chick at this point? I mean she is trying to learn the secret of your strength and betray you and have you captured by your enemies. Is this really the woman you want to hang with? Is she really that beautiful? Is the sex really that good? Are you really that dumb and shallow?

And Delilah - you didn't have a better plan for seeking out this secret other than asking Samson outright. Weren't you concerned that he was on to you since each time he told you, you tied him up in his sleep and woke him to a gang of thugs ready to take him down? And when he wouldn't give you a truthful answer you turned to begging and whining and nagging? Let's just say if I were head of the CIA, I would not hire you as one of our operatives.

And then this is where I am just flabberghasted. Samson tells her his secret! Why, you ask? Because "with such nagging she prodded him day after day until he was tired to death." Seriously, Dude, what were you thinking!?! Maybe he was thinking that God really wasn't the source of his strength like he had been taught from birth. Maybe he thought he was really just that strong and powerful and all that on his own. Maybe he was trying to go to sleep and just wanted her to leave him alone. (Why wasn't kicking her out of your bed an option Sammy?) Or maybe he was drunk. Really the best option I can come up with is that he was just that stupid.

So she shaves his hair that has never been cut since birth and wakes him up to a room of Philistines who subdue him, gouge out his eyes, bind him with bronze shackles and throw him in prison. I don't feel badly for Samson because he brought this on himself. But he does get his revenge when the Philistines parade him out in their temple and he pushes down the support pillars to bring down the temple on himself and all the rulers and several thousand Philistines who were in it. "Thus he killed many more when he died than while he lived." (Judges 16:30)

And God fulfilled the prophecy from when Samson was born: "...he will begin the deliverance of Israel from the hands of the Philistines." So I guess the moral of the story is that God will fulfill his plan no matter how dumb the people he chooses to employ are.
