'Behalf' in the Bible

And he exercises all the authority of the first beast on behalf of him, and he causes the earth and those who live in it to worship the first beast {whose fatal wound had been healed}.

And he deceives those who live on the earth because of the signs that it has been granted to him to perform on behalf of the beast, telling those who live on the earth to make an image to the beast who has the wound of the sword and [yet] lived.
