And Gideon said to God, If You will save Israel by my hand, as You have said,

For lo, you shall conceive and bear a son. And no razor shall come upon his head. For the child shall be a Nazarite to God from the womb. And he shall begin to deliver Israel out of the hand of the Philistines.

And he told her all his heart, and said to her, A razor has not come on my hair, for I am a Nazirite to God from my mother's womb. If I am shaven, then my strength will go from me, and I will become weak and be like any man.

And Samson called to Jehovah and said, O, Lord Jehovah, remember me, I pray You, and strengthen me, I pray You, only this once, O God, so that I may be at once avenged of the Philistines for my two eyes.
