The man has imposed on you, because this machine is worthless .

这个人欺骗了你，因为这台机器毫无用处。

Now therefore know this and consider what you should do, for harm is determined against our master and against all his house, and he is such a worthless man that one cannot speak to him.

所以你当筹划，看怎样行才好；不然，祸患定要临到我主人和他全家。他性情凶暴，无人敢与他说话。
