Jeremiah 50:16

Cut off the sower from Babylon— Babylon resembled a country walled in, rather than a city; the walls, according to Herodotus, being sixty miles in compass. Within this large circuit a great deal of ground was cultivated with corn; so that enough grew within the walls to support the inhabitants during a long siege. Others understand by Babylon here, not the city only, but the whole province: the latter part of the verse is spoken of the Babylonish allies. See Isaiah 13:14.
