One day, when Abba Agathon was on his way to town to sell small utensils, he saw a leper sitting on the roadside, who asked: "Where are you going?" Abba Agathon replied: "To town, to sell these things. Then he said: "Do me a favor, and take me there." So he picked him up and carried him to the town. Then he said: "Put me down in the place where you intend to sell those things." So he did. And when he sold one item, the leper asked: "How much did you sell that for?" So he told him how much it was. Then he said: "Buy me something nice with the money you made." So he bought it. He sold another item. Then the leper asked: "And how much did you sell that for?" So he told him the price. Then he said: "Buy me something else." So he bought it. After selling everything, Abba Agathon wanted to go. Then the leper asked: "Are you going back now?" "Yes", he replied. Then, the leper said: "Do me a favor once again, and carry me back to where you found me this morning." So, Abba Agathon carried him back to the place where he found him earlier. Then the leper said: "You are blessed, Agathon! Blessed by the Lord of heaven and earth!" When Abba Agathon looked up to see who had spoken, he saw nobody. It was an angel of the Lord who had come to test him.
