The rabbis point out the irony of two pagan nations able to live together in the land, but two shepherd families called “righteous” can’t share the land.
It’s a great shame.
And there was strife between the herdsmen of Abram’s livestock and the herdsmen of Lot’s livestock. The Canaanites and the Perizzites then dwelt in the land.
Genesis 13:7 (NKJV)
