'With Authority' in the Bible

And they were all greatly surprised, so that they put questions to one another, saying, What is this? a new teaching! with authority he gives orders even to the unclean spirits, and they do what he says.

And they were surprised at his teaching, for his word was with authority.

And wonder came on them all and they said to one another, What are these words? for with authority and power he gives orders to the evil spirits and they come out.
