Honor is defined in the dictionary as "esteem, respect, reverence." The first Commandment relating to human relationships was to "honor your father and mother." (Exodus 20) This even included giving material assistance to them if they were in need.
By Jesus' time the Pharisees and teachers of the law had twisted the command and excused individuals for disobeying it by saying that "whatever help you might otherwise have received from me is a gift (corban) devoted to God." I'm amazed about the similarity between this and the attitude among JWs today. Parents who are disfellowshipped are shunned and ignored all in the name of religious faith. JWs rationalize that since "Jehovah is our father and the organization is our mother" they have no obligation toward their fleshly parents. But as Jesus warned the religious leaders of his day: "Thus you nullify the word of God for the sake of your tradition. You hypocrites! Isaiah was right when he prophesied about you: 'These peope honor me with the lips but their hearts are for from me. They worship me in vain; their teachings are but rules taught by men." (Matthew 153-9)
