Luke 21:1-7

1 Looking up, Jesus saw people, especially the rich, dropping their gifts into the temple offering box.
2 He noticed a poor widow drop in two small coins.
3 He said, "I can guarantee this truth: This poor widow has given more than all the others.
4 All of these people have given what they could spare. But she, in her poverty, has given everything she had to live on."
5 Some [of the disciples] were talking about the temple complex. They noted that it was built with fine stones and decorated with beautiful gifts. So Jesus said,
6 "About these buildings that you see--the time will come when not one of these stones will be left on top of another. Each one will be torn down."
7 The disciples asked him, "Teacher, when will this happen? What will be the sign when all this will occur?"
