ה אמר רב חסדא ל"ק כאן שהרגו דרך ירידה כאן שהרגו דרך עלייה דרך ירידה דישראל גלי איהו נמי סגי ליה בגלות דרך עלייה דישראל פטור הוא נהרג
5 Rav Hisda said: This is not a difficulty! Here [where he is exiled] is where he killed in a downward motion, and here [where he is not exiled] is where he killed in an upward motion. [I.e:] If [he killed him] in a downward motion, [in which case] an Israelite would be exiled, then exile should be enough for the [resident foreigner] as well. If [he killed him] in an upward motion, [in which case] an Israelite is exempt, then the resident foreigner is put to death.
