'One' in the Bible

My loved one, it is my prayer that you may do well in all things, and be healthy in body, even as your soul does well.

My loved one, you are doing a good work in being kind to those brothers who come from other places;

Dear friend, do not imitate what is evil, but what is good. The one who does good is of God; the one who does evil has not seen God.

Peace be to you. The friends [here] greet you. Greet the friends [personally] by name.
