It was said about John the Little that one day he said to his older brother: "I want to be free from care and not to work but to worship God without interruption." And he took his robe off, and went into the desert. After staying there one week, he returned to his brother. And when he knocked at the door, his brother asked without opening it: "Who is it?" He replied: "It's John, your brother." The brother said: "John has become an angel and is not among people anymore." Then he begged and said: "It's me!" But his brother did not open the door and left him there in distress until the next morning. And he finally opened the door and said: "If you are a human being, you have to work again in order to live." Then John repented, saying: "Forgive me, brother, for I was wrong."
