Genesis 36:7
For their riches were more than that they might dwell together; and the land wherein they were strangers could not bear them because of their cattle.
Cross-reference
In Genesis 36:43, the Edomite chiefs are settled 'in the land of their possession' — the outcome Esau's departure here sets in motion.
Genesis 13:6 describes the same land scarcity forcing Abram and Lot to separate — a direct parallel to Esau and Jacob.
In Genesis 37:1, Jacob remains in Canaan — the immediate narrative contrast. Esau leaves; Jacob stays in the land of sojourning.
In Genesis 17:8, God gives 'the land of your sojournings' — Canaan — to Abraham's line forever. Esau here departs that very land.
In Genesis 28:4, Isaac blesses Jacob with 'the land of your sojournings.' Esau leaving that same land contrasts with Jacob inheriting it.
In Genesis 25:33, Esau sells his birthright, which included claim to the promised land. His departure to Seir is the long-term consequence.
