Christians should keep away from any brother __________ according to Paul.

Paul, a disciple of Jesus and an apostle, wrote letters to early Christian communities that are now part of the New Testament in the Bible. In one of his letters, he advised Christians to avoid associating with a brother who is "living in idleness". This means to avoid being close friends with someone who is lazy and not working to support themselves. Paul believed that it was important for each person to contribute to society and not be a burden on others. He encouraged Christians to live responsible and productive lives and to avoid those who do not follow this principle.
