Jesus, in the temple, allows himself to sit in front of the trunk to see what people are giving. Jesus calls his disciples to take a practical lesson: the rich gave a lot and impressed the witnesses, but not Jesus. A poor widow arrives discreetly, “a quarter of a penny”.
Jesus let her do it and he added to his disciples. The rich have put their superfluous, but she has put his necessities, everything she had, and all she had to live. Mark 12:44
