'Authority' in the Bible

They were astonished at his teaching, for he taught them as having authority, and not as the scribes.

They were all amazed, so that they questioned among themselves, saying, "What is this? A new teaching? For with authority he commands even the unclean spirits, and they obey him!"

But that you may know that the Son of Man has authority on earth to forgive sins" -- he said to the paralytic --

and to have authority to heal sicknesses and to cast out demons:

He called to himself the twelve, and began to send them out two by two; and he gave them authority over the unclean spirits.

Jesus summoned them, and said to them, "You know that they who are recognized as rulers over the nations lord it over them, and their great ones exercise authority over them.

and they began saying to him, "By what authority do you do these things? Or who gave you this authority to do these things?"

Jesus said to them, "I will ask you one question. Answer me, and I will tell you by what authority I do these things.

They answered Jesus, "We don't know." Jesus said to them, "Neither do I tell you by what authority I do these things."

"It is like a man, traveling to another country, having left his house, and given authority to his servants, and to each one his work, and also commanded the doorkeeper to keep watch.
