Luke 21:1-7

And he looked up, and saw the rich men that were casting their gifts into the treasury. And he saw a certain poor widow casting in thither two mites. And he said, Of a truth I say unto you, This poor widow cast in more than they all: for all these did of their superfluity cast in unto the gifts; but she of her want did cast in all the living that she had. And as some spake of the temple, how it was adorned with goodly stones and offerings, he said, As for these things which ye behold, the days will come, in which there shall not be left here one stone upon another, that shall not be thrown down. And they asked him, saying, Teacher, when therefore shall these things be? and what shall be the sign when these things are about to come to pass?
