Thanks for your question.
The story of the Widow’s mites is found in Matthew 12:41-43
41 And he sat down opposite the treasury and watched the people putting money into the offering box. Many rich people put in large sums.
42 And a poor widow came and put in two small copper coins, which make a penny.
43 And he called his disciples to him and said to them, “Truly, I say to you, this poor widow has put in more than all those who are contributing to the offering box.
44 For they all contributed out of their abundance, but she out of her poverty has put in everything she had, all she had to live on.”
The point of the story is that the wealthy were giving out of a need to be seen and for personal prestige and they gave only a small fraction of their wealth. The poor widow cast into the treasury box two small copper coins [mites] which was all that she had.The moral of the story is that the widow who gave all in humility and quietly was held in high esteem by God.
I hope you have found this helpful.
