Mark 12:42-44 NIV

42 But a poor widow came and put in two very small copper coins, worth only a few cents.
43 Calling his disciples to him, Jesus said, “Truly I tell you, this poor widow has put more into the treasury than all the others.
44 They all gave out of their wealth; but she, out of her poverty, put in everything—all she had to live on.”
