Due to what reason was the First Temple destroyed? It was destroyed due to the fact that there were three matters that existed in the First Temple: Idol worship, forbidden sexual relations, and bloodshed... However, considering that the people during the Second Temple period were engaged in Torah study, observance of mitzvot, and acts of kindness, and that they did not perform the sinful acts that were performed in the First Temple, why was the Second Temple destroyed? It was destroyed due to the fact that there was wanton hatred during that period. This comes to teach you that the sin of wanton hatred is equivalent to the three severe transgressions: Idol worship, forbidden sexual relations and bloodshed... § It was Rabbi Yoḥanan and Rabbi Elazar who both said: In the case of the former, the people in the First Temple era, whose sin was exposed and no attempt was made to disguise their conduct, the end of their punishment was exposed, and the prophet informed them that they would return to their land in seventy years. In the case of the latter, the people in the Second Temple era, whose sin was not exposed; rather, they attempted to disguise their conduct, the end of their punishment was not exposed.
