What does Judges 16:18 mean?
Delilah knew this conversation with Samson was different from the others. He probably thought her previous questions were part of a teasing lover's game (Judges 16:6–14). Over time, she lulled him into a false sense of security and applied incredible emotional pressure. Finally, sick at heart to prove himself to the woman he loved (Judges 16:15–17), he had been open with her like never before. He had been genuine. Samson likely thought Delilah loved him too much to do something as drastic as shaving his head. She could tell he kept nothing back from her.Had Samson and Delilah had been a committed married couple going through counseling together, this might have been a positive breakthrough leading to lasting intimacy. Instead, it is a breakdown leading to Delilah's fortune. She knows she has broken Samson, at last. The men who'd proposed to offer her riches if she captured him would have to pay up (Judges 16:4–5).
During their previous rounds of their "game," Delilah had kept men waiting to ambush Samson if he had lost his power. That detail wasn't noted in the last attempt (Judges 16:14). Now that she's entirely sure of her victory, Delilah contacts the Philistine nobles who hired her and tells them to bring their men and her money. They do so, eager to pounce on Samson as soon as he is weak.
The price of Samson's constant carelessness with women was a heart always drawn to follow his physical desires (Proverbs 5:3–14). Rather than seeking the Lord's guidance, he was led by his lesser instincts, and into destruction (Judges 16:19–21; James 1:15). Even so, God uses even Samson's failure to continue to work out His plan: shaking Israel free from submission under the Philistines (Judges 13:5; 14:4). Philistine arrogance and complacency will provide an opportunity for one last vengeful strike from Samson (Judges 16:22, 28–30).
