'With Authority' in the Bible

And they were all amazed, so that [they began] to discuss with one another, saying, "What is this? A new teaching with authority! He even commands the unclean spirits and they obey him."

And they were astounded at his teaching, because {he spoke} with authority.

And amazement came upon [them] all, and they began to talk with one another, saying, "What word [is] this? For he commands the unclean spirits with authority and power, and they come out!"
