Summary: If you lay your head in Delilah's lap it will be bring destruction.
Sampson had a strong love for Delilah but it seems she did not have love for him.
There is a great analogy here between Sampson and Delilah and the church or saint of God and the world.
Delilah was a philistine woman, she was a whorish woman.
She would be a type and shadow of the world…
Sampson was a man used by God, a judge of Israel and a man that was called to be Holy from his birth.
If you fall to Delilah's charm even though it may appear beautiful and fulfill and satisfy your lusts and desires you will come to a place that is dangerous.
Delilah will try to entice you and woo you to fall asleep in her lap but what dangers lie ahead..
If you lay your head in Delilah's lap it will be bring destruction.
As you lay your head in Delilah’s lap her seduction will try to win you and pull you from your strength.i.e. "If you play with fire long enough you will get burnt."
Judges 16:13 (quickview)  And Delilah said unto Samson, Hitherto thou hast mocked me, and told me lies: tell me wherewith thou mightest be bound. And he said unto her, If thou weavest the seven locks of my head with the web.
Judges 16:16-17 (quickview)  And it came to pass, when she pressed him daily with her words, and urged him, so that his soul was vexed unto death; (17) That he told her all his heart, and said unto her, There hath not come a razor upon mine head; for I have been a Nazarite unto God from my mother's womb: if I be shaven, then my strength will go from me, and I shall become weak, and be like any other man.
4 times she pulled and finally won and Sampson was a fallen man. Maybe he thought within him I can’t fall, I feel God, I am used of God but what a danger.
