Two Rabbis disputing the question maintained: one, that it was not fit to come within a hundred cubits of a leper; the other, within four cubits, when he stood between them and the wind. Another would not eat an egg if laid in a courtyard where a leper was. One, when he saw a leper, assailed him with stones, saying: “Off to thy own place, lest thou defile others,” etc.
