Another matter: “One hundred and twenty-seven provinces” – Rabbi Yuda and Rabbi Neḥemya: Rabbi Yuda said: He conquered seven that were as difficult as twenty; he conquered twenty that were as difficult as one hundred. Rabbi Neḥemya said: He took troops from seven and conquered twenty; he took troops from twenty and conquered one hundred. How did he conquer them? Rabbi Yuda and Rabbi Neḥemya: Rabbi Yuda said: Like a semi-circle, you conquer the outer areas and the inner areas become conquered by themselves. Rabbi Pinḥas said: The world is circular. Rabbi Avun said: It is like the surface of a two-kav vessel.14A kav is measure of volume. A two-kav vessel contains slightly less than three liters. Rabbi Neḥemya said: It is like an aqueduct; you conquer the outsides and the insides are conquered by themselves.
