It is written in the Talmud (Gittin 55b) that the Second Temple was destroyed because of senseless hatred. The Talmud mentions an incident involving Bar Kamtza and an unnamed individual who hated each other. This man had a friend named Kamtza and an enemy named Bar Kamtza. One day the man made a banquet. The man’s attendant accidently invited Bar Kamtza, who accepted the invitation and went to the banquet. When the host saw Bar Kamtza he asked him, “Why you are here? You are my enemy. Get up and get out.” Bar Kamtza offered to pay for his meal, then for half of the banquet, and finally the entire banquet. His requests were refused. The host grabbed hold of Bar Kamtza and threw him out. The rabbis were there and did not rebuke the man. Bar Kamtza subsequently went to the Caesar and told him that the Jews are rebelling.
