Adoni-bezek said, “Seventy kings with their thumbs and their big toes cut off used to gather up scraps under my table; as I have done, so God has repaid me.” So they brought him to Jerusalem and he died there.

So God subdued on that day Jabin the king of Canaan before the sons of Israel.

But he said to me, ‘Behold, you shall conceive and give birth to a son, and now you shall not drink wine or strong drink nor eat any unclean thing, for the boy shall be a Nazirite to God from the womb to the day of his death.’”

So he told her all that was in his heart and said to her, “A razor has never come on my head, for I have been a Nazirite to God from my mother’s womb. If I am shaved, then my strength will leave me and I will become weak and be like any other man.”

Then Samson called to the Lord and said, “O Lord God, please remember me and please strengthen me just this time, O God, that I may at once be avenged of the Philistines for my two eyes.”
