'Defame' in the Bible

It is enough for the disciple to become like his teacher, and the slave like his master. If they have called the head of the house 'Beelzebul,' how much more will they defame the members of his household!

Blessed [morally courageous and spiritually alive with life-joy in God’s goodness] are you when people hate you, and exclude you [from their fellowship], and insult you, and scorn your name as evil because of [your association with] the Son of Man.
