Samson single-handedly crushed the Philistine army . In turn , the Philistines bribed his lover, Delilah , to reveal Samson's source of strength ; his hair, uncut since birth. While Samson was asleep , Delilah signaled a waiting Philistine , who sheared the hero, rendering him helpless. Honthorst intensified the narrative by having Delilah cut Samson's hair herself . An old woman also warns us against waking him , which implicates the viewer in Samson's emasculation.
