I now want to reply to the matters you people wrote me about. It is [a] good [idea] for a man not to get married.

Now to those people who are not married [Note: This probably refers to all unmarried people, and not just to widowers, as some think], or who are widows, I say it is [a] good [idea] for them to remain like me [i.e., single. See verse
