'Works' in the Bible

And when sabbath was come he began to teach in the synagogue, and many hearing were amazed, saying, Whence has this man these things? and what is the wisdom that is given to him, and such works of power are done by his hands?

And Herod the king heard of him (for his name had become public), and said, John the baptist is risen from among the dead, and on this account works of power are wrought by him.
