The very first reference to what we might consider a honeymoon comes from the Bible in Deuteronomy 25:5 where it says, “When a man has taken a new wife, he shall not go out to war or be charged with any business; he shall be free at home one year, and bring happiness to his wife whom he has taken.” Don’t you wish we could still follow that precept?!
The Merriam-Webster dictionary reports the etymology of honeymoon as coming from "the idea that the first month of marriage is the sweetest."
Another source for the term may come from the ancient tradition in many parts of Europe where newly married couples were provided with enough mead to last a month, thus ensuring happiness and fertility. (Mead is a light alcoholic beverage made from fermented honey.) Thus, the combination of “honey,” and the idea of a lunar month, “moon,” to get “honeymoon;” or as the French say, "lune de miel."
