When it is already part of the verb, its use here creates emphasis on the "you" as we might say "you yourselves." It sometimes precedes a verbal adjective or infinitive where it is not part of the verb. It is plural.

master , -- The word translated as "master" is the same word that is often translated as "Lord" or "the Lord" in the NT. It also means "lord," "master of the house," and "head of the family." It is the specific terms for the master of slaves or servants, but it was a common term of respect both for those in authority and who were honored. It was the term people used to address Christ, even though he had no formal authority. Today, we would say "boss" or "chief." For the sake of consistency, this should be the Greek word translated as "master."

from --  The Greek preposition translated as "of" means "out of" or "from."
