Ezra 3: Weeping and Joy

Sometimes the same event can lead to a variety of emotions. When the former exiles finished the foundation for the new temple, the audience included people who had seen the first temple before it was destroyed (50-70 years earlier). This explains their weeping in verse 12 (And tears do not always mean that we are sad, do they?). The shouts of joy came from people who had only seen that which was before their eyes. Such experiences can produce great results. Be aware of reasons why others may express different emotions than you.
