'Master of the House' in the Bible

A disciple is doing well if he can be [as good] as his teacher, and the slave [as good] as his master. If they have called the master of the house [i.e., Jesus] Beelzebub [i.e., the chief of evil spirits. See Mark 3:22], how much more [likely] will they call members of his household [i.e., the disciples] the same thing!
