Speak unto the children of Israel, and say unto them, When either man or woman shall separate themselves to vow a vow of a Nazarite, to separate themselves unto the LORD:

Tell the people of Israel, "When a person, whether a man or a woman, decides to make a special promise called a Nazarite vow to dedicate themselves to God, they must do so."
