Jesus was sitting across from the tithe box at the Temple. He saw all the people dropping their money into it – the rich were putting in a lot. A poor widow came along and put in just two tiny coins, barely enough to buy a loaf of bread. Jesus called his disciples to notice this and said “Truly, this poor widow has donated far more than anyone else. They had given out of their excess, but she has given out of her lack. She has given everything that she has to live on.”
