What does Ezra 3:12 mean?

But many of the older priests, Levites, and family leaders who had seen the first temple cried loudly when they saw the new foundation, even as many others shouted for joy. Ezra 3:12 - Modern Text Bible

(Some of the older folks wept because they remembered the old temple and felt the weight of loss and hope mixed together, while others were just excited for the new beginning.)
