Luke 21:4 Meaning

2And he saw also a certain poor widow casting in thither two mites.

3And he said, Of a truth I say unto you, that this poor widow hath cast in more than they all:

4For all these have of their abundance cast in unto the offerings of God: but she of her penury hath cast in all the living that she had.

5And as some spake of the temple, how it was adorned with goodly stones and gifts, he said,

6As for these things which ye behold, the days will come, in the which there shall not be left one stone upon another, that shall not be thrown down.
