And it came to pass, when she pestered him daily with her words and pressed him, so that his soul was vexed to death, that he told her all his heart, and said to her, “No razor has ever come upon my head, for I have been a Nazirite to God from my mother’s womb. If I am shaven, then my strength will leave me, and I shall become weak, and be like any other man.” Judges 16:16-17

Most likely you know the story of Samson and Delilah.

Samson was a judge of Israel. An angel prophesied his birth to his barren mom along with instructions to her on what to eat and drink.

As I read about his exploits I can’t help but think he wasted his incredible strength on silly endeavors – a bit of a show-off. I mean no disrespect.
He never rallied the people of Israel behind him to rid them of the Philistine oppression.
In fact, he chose a wife from the Philistines, the enemy of Israel at the time, and even though it was of the Lord it caused him some problem.
He frequented prostitutes and eventually allowed himself lulled by Delilah to reveal his source of strength.
His revelation to her is the fulfillment of casting your pearls before the swine (Matt 7:6).
Samson is captured, tortured, and enslaved as an object of ridicule.

The bright side of his life seems to come from his death.
Then Samson called to the Lord, saying, “O Lord God, remember me, I pray! Strengthen me, I pray, just this once, O God, that I may with one blow take vengeance on the Philistines for my two eyes!” And Samson took hold of the two middle pillars which supported the temple, and he braced himself against them, one on his right and the other on his left. Then Samson said, “Let me die with the Philistines!” And he pushed with all his might, and the temple fell on the lords and all the people who were in it. So the dead that he killed at his death were more than he had killed in his life. Judges 16:28-30

There are lessons to gain from Samson’s life.
Always give God the credit for the gift in your life. Be humble. Complete your tasks. Live towards a holy, righteous life before the Lord.
Be separate and sanctified from the world.
Honor God.

As Paul would say centuries later as he explains the armor of God – be strong in the Lord and in the power of His might. Eph 6:10
