Once three brothers came to visit an old man in Scetis and one of them said to him, “Abba, I have committed to memory the Old and New Testaments.” And the old man answered, “You have filled the air with words.” The second one said to him, “I have written out the Old and New Testaments with my own hands.” He said, “And you have filled the window-ledge with manuscripts.” Then the third said, “The grass is growing up my chimney.” And the old man replied, “You have driven away hospitality.”
Once two brothers came to a certain old man. It was his custom not to eat every day but when he saw them he received them joyfully and said, “A fast has its own reward, but he who eats for the sake of love fulfils two commandments: he leaves his own will and he refreshes his brothers.”
It was said of an old man that he dwelt in Syria on the way to the desert. This was his work: whenever a monk came from the desert, he gave him refreshment with all his heart. Now one day a hermit came and he offered him refreshment. The other did not want to accept it, saying he was fasting. Filled with sorrow, the old man said to him, “Do not despise your servant, I beg you, do not despise me, but let us pray together. Look at the tree which is here; we will follow the way of whichever of us causes it to bend when he kneels on the ground and prays.” So the hermit knelt down to pray and nothing happened. Then the hospitable one knelt down and at once the tree bent towards him. Taught by this, they gave thanks to God.
