Jesus when talking to Peter.
Matthew 16:23 Jesus turned and said to Peter, "Get behind me, Satan (Satana)!
Jesus when talking to the Lucifer.
Matthew 4:10 Then saith Jesus unto him, Get thee hence, Satan (Satana): for it is written, Thou shalt worship the Lord thy God, and him only shalt thou serve.
Isn’t that interesting!
What is this, St. Groundhog's Day? We went through this exact discussion exactly one week ago on a different thread.
Satana, “Satan,” derives from the Aramaic root sata, and means “to slip,” “to slide,” “to deceive,” “to miss the mark,” and “to cause one to be misled or go astray.” In Aramaic, calling an individual a “satan” means that the person is going astray or misleads. If Jesus had intended to refer to St. Peter as the devil the words he could have used were Lucifer, Beelzebub, Ahriman, Mephistopheles, or Phosphoros.
Peace be with you
