“But if that evil servant shall say in his heart, ‘My lord delays', and shall begin to beat his fellow-servants, and shall eat and drink with the drunken,”
However, if the one appointed turns out to be an evil servant, and begins to consider that his Master is delaying his coming (although that should really have made no difference to his behaviour), and thus begins to beat his fellow-servants and indulge in riotous excess (note the inference that such behaviour is displeasing to the Lord), he will in the end be caught out.
