Mat 14:31 Go.
Depart, [all of you]!
Here, a single word is spoken to the demons that inflict a man, casting them into pigs. For more on understanding "demons", you can read this article on the Greek word for "demon" and word that seem related words in Christian teaching or to this article on modern language equivalents.
The term translated as "go" means "to lead under", "to go under," or "to depart." It means to bring under one's power and to lead on, but Christ usually uses it to mean "go away" and "depart." It is a common word for Christ to use. Here it is in the 2nd person, plural in the form of a command. In English, we cannot see the number of people a simple command is aimed as so adding "all of you" captures additional information in the Greek verb.
