Joshua 21:42

These cities were every one with their suburbs Namely, two thousand cubits on every side round each city, as was ordered, Numbers 35:5; and it certainly was a large proportion for this tribe. But God intended that an ample provision should be made for his ministers, to put honour on those whom he foresaw many would despise; and that, being free from outward cares and distractions, they might more entirely and fervently devote themselves to the service of God.
