17 That he told her all his heart, and said unto her. There hath not come a rasor upon mine head; for I have been a Nazarite unto God from my mother's womb: if I be shaven, then my strength will go from me, and I shall become weak, and be like any other man.
[AD 397] Ambrose of Milan on Judges 16:10-17
But last of all the wanton woman complaining that she had been so often deceived, and grieving that her lover deemed her unworthy to be entrusted with his secret, and that under her pretext of succour her treacherous purpose was suspected, won his confidence by her tears. By this means, and because also it was ordained that this man of hitherto unshaken fortitude should fall into calamity, Samson was touched and opened to her his heart. He told her that he possessed within him the power of God, that he was sanctified to the Lord, and that by His command he let his hair grow, and that if it were shorn, he would cease to be a Nazarite, and lose the use of his strength. The Philistines having discoverd through her means the man's weakness, bring her the reward of her perfidy, thus binding her to the commission of the crime.
