Read Judges 13-16:31
Again the Israelites did evil in the eyes of the LORD, so the LORD delivered them into the hands of the Philistines for forty years. (Judges 13:1)Again ... The vicious circle continues ...
A certain man of Zorah, named Manoah, from the clan of the Danites, had a wife who was childless, unable to give birth. The angel of the LORD appeared to her and said, "You are barren and childless, but you are going to become pregnant and give birth to a son. Now see to it that you drink no wine or other fermented drink and that you do not eat anything unclean. You will become pregnant and have a son whose head is never to be touched by a razor because the boy is to be a Nazirite, dedicated to God from the womb. He will begin to deliver Israel from the hands of the Philistines. (Judges 13:2-5)"Despite the tremendous physical strength God blessed Samson with for the purpose of delivering Israel from the Philistines Samson blows it and doesn't really use his gift to benefit his people. He instead goes his own way satisfying his own interests. Even though Samson didn't live up to his potential God achieves his ultimate purpose in weakening the Philistines so they can be defeated latter under the leadership of Samuel and his people freed from the slavery of the Philistines.
... Samson went down to Timnah and saw there a young Philistine woman. (Judges 14:1)
... Samson said to his father, "Get her for me. She's the right one for me." (His parents did not know that this was from the LORD, who was seeking an occasion to confront the Philistines; for at that time they were ruling over Israel.) (Judges 14:3-4)
