Samson said, Let me die with the Philistines. He bowed himself with all his might; and the house fell on the lords, and on all the people who were therein. So the dead that he killed at his death were more than those who he killed in his life.
We might suppose that the Philistines would have been careful to keep their captive’s hair cropped. Whether because they considered their blind slave incapable of escaping, or because they failed to recognize the importance of his hair, they did not. They were in their own way as blind as Samson. Along with his hair, Samson’s dedication to Yahweh, which his hair symbolized, began to return (cf. Judges 16:28). This was the real reason his strength returned.
