Jesus told them that a poor widow’s tiny sacrificial offering was worth more in God’s sight than large amounts of money from rich people.

Mark 12:41-44

41 Later, Jesus sat down in the Temple courtyard opposite the boxes in which people put offerings. As he was sitting there, he watched as all the people put money in the box. Many rich people put in large amounts of money. 42 Then a poor widow came along and put in two small copper coins, which had a very small value. 43-44 43-44He gathered his disciples around him and said to them, “The truth is that these other people have a lot of money, but they gave only a small part of it. But this woman, who is very poor, has put in all the money that she had to pay for the things she needs. So God considers that this poor widow has put more money into the box than all the other people!”
