Judges 15:6
Then the Philistines said, Who hath done this? And they answered, Samson, the son in law of the Timnite, because he had taken his wife, and given her to his companion. And the Philistines came up, and burnt her and her father with fire. Then the Philistines said, Who hath done this? And they answered, Samson, the son in law of the Timnite, because he had taken his wife, and given her to his companion. And the Philistines came up, and burnt her and her father with fire.
Samson grew up near Zorah beside the Philistines and mingled with them on friendly terms, forming intimacies that darkened his whole life. He set his affections on a young Philistine woman of Timnath, and when his God-fearing parents dissuaded him he answered only that she pleased him well and insisted on having her, until they yielded. He married her just as he was entering manhood, when he should have remained true to God in his divine mission as judge and deliverer of Israel, and by that marriage he joined himself to the enemies of Israel from self-pleasing rather than to glorify God.
When Samson found his wife given to another he took revenge by wasting the fields and vineyards of the Philistines, and in return the Philistines burned his wife and her father with fire. Their own threats had driven her to the deceit that began the trouble, yet they murdered her and her father in this barbarous way. That murder moved Samson in anger to attack the Philistines and strike them with a great slaughter before withdrawing to the rock Etam in Judah. The whole course shows what follows giving free rein to passion instead of choosing obedience and self-control, a path that led Samson to shame, disaster, and death.
