The Source of Samson's Strength
Samson's story was remembered to teach us a specific lesson. God was the true, ultimate source of his strength. Samson's uncut hair was simply the sign that he was obeying God's command for him to be a Nazarite. God's strength was the power behind Samson.
Then Samson prayed to the Lord, "Sovereign Lord, remember me. Please, God, strengthen me just once more, and let me with one blow get revenge on the Philistines for my two eyes." Then Samson reached toward the two central pillars on which the temple stood. Bracing himself against them, his right hand on the one and his left hand on the other, Samson said, "Let me die with the Philistines!" Then he pushed with all his might, and down came the temple on the rulers and all the people in it. Thus he killed many more when he died than while he lived.
- Judges 16:28-30 (NIV)
