'Lady' in the Bible

The elder [of the church addresses this letter] to the elect (chosen) lady and her children, whom I love in truth—and not only I, but also all who know and understand the truth—

Now I ask you, lady, not as if I were writing to you a new commandment, but [simply reminding you of] the one which we have had from the beginning, that we love and unselfishly seek the best for one another.
