Finally then, brothers, we beg and exhort you in the Lord Jesus, that as you received from us how you ought to walk and to please God, that you abound more and more.
so ye would abound more and more: that is, be more and more in the exercise of every grace, and in the discharge of every duty, making advances in holiness of life, and perfecting it in the fear of God. Beza's ancient copy, and another manuscript, as also the Alexandrian copy, and some others, add between the preceding, and this last clause, "as ye also walk"; and so the Vulgate Latin and Ethiopic versions seem to have read; commending them for their present and past walk and conversation, in order to persuade and encourage them to go forward.
