'With Authority' in the Bible

and they were amazed, one and all, so that they began to discuss among themselves, saying - What is this? New teaching! With authority, to the impure spirits also, he giveth orders, and they obey him!

and they were being struck with astonishment at his teaching, because, with authority, was his word.

And amazement came upon all, and they began to converse one with another, saying - What is this word, that, with authority and power, he giveth orders unto the impure spirits, and they go forth?
