Judges 15:5
And when he had set the brands on fire, he let them go into the standing corn of the Philistines, and burnt up both the shocks, and also the standing corn, with the vineyards and olives.

Samson was the promised son given to Manoah, a Nazarite from birth whose extraordinary physical strength did not depend on his well-knit sinews but on his condition as a Nazarite symbolized by his unshorn hair. The burning of the Philistines' grain falls in the time when he was entering upon manhood to execute his divine mission as judge and deliverer of Israel, when above all others he should have been true to God. Instead he mingled on friendly terms with the Philistines near Zorah, formed intimacies that darkened his whole life, and married a young woman of Philistine Timnath because she pleased him well, against the dissuasion of his God-fearing parents.
Despite his great physical strength and God's purpose for him, he failed to govern his passions, and his choices led toward shame, disaster, and death. The burning was his revenge after the wife he had obtained by transgressing God's command proved treacherous before the close of the marriage feast and had been given to another by the time he returned for her. By wasting all the fields and vineyards of the Philistines he provoked the Philistines to murder her, although their own threats had driven her to the deceit with which the trouble began. Moved to anger by that barbarous murder, he then attacked the Philistines and smote them with a great slaughter.
