Final answer:
Samson's greatest victory against the Philistines was toppling their temple, as noted in JG 16:27-30, where he brought down the temple pillars, dying in the process along with many Philistines.
Step-by-step explanation:
Samson's greatest victory against the Philistines was not through killing a lion, defeating them in a wrestling match, or burning their crops. His most definitive triumph is recorded in the Bible as C. Toppling their temple. This event is documented in the Book of Judges, specifically JG 16:27-30, where Samson, after being captured by the Philistines, regains his strength and pulls down the pillars of a Philistine temple, leading to his death and that of many Philistines. This act of strength and sacrifice marked his ultimate victory against the Philistines.
