Judges 13:4 - Coke's Commentary on the Holy Bible

Now, therefore, beware, &c.— As Samson was to be a perfect Nazarite unto God, from the womb to the day of his death, Joshua 13:7 his mother is commanded to live as the Nazarites did, (Numbers 6.) while she carried him in her womb, and, most likely, while she nursed him; because a child in the womb, and its mother, live by the same nourishment.
