Mar (the master) has said, "From dawn to the appearance of the sun is
five miles." How is this proved? It is written (Gen. xix. 15), "When the
dawn arose the angels hurried Lot;" and it is added (verse 25), "The sun
was risen upon the earth when Lot entered into Zoar." And Rabbi Chanena
said, "I myself have seen that place, and the distance is five miles."
