ephesians, is the forty-ninth book in the christian bible, and the tenth in the new testament. this book is thought to have been written by the apostle paul to the people of ephesus while he was imprisoned in rome, around 62 a.d. however, the words "in ephesus" do not appear in the best and earliest hand copies of the letter, leading most textual critics, like bart ehrman, to regard the words "in ephesus" as a later addition. copies of the letter may have been sent to other churches also, since it contains no personal references to people at ephesus.
