Genesis 25:28

And Isaac loved Esau, because he did eat of his venison: but Rebekah loved Jacob.

Cross-reference

In Genesis 27:4, Isaac asks Esau to prepare wild game so he can bless him — directly continuing the preference established here, which Rebekah then exploits.

In Genesis 27:6, Rebekah overhears Isaac tell Esau to prepare game — she already knows Isaac's love for Esau's wild game and acts on it.

In Genesis 27:19, Jacob presents 'my game' to Isaac, deliberately exploiting Isaac's known love for Esau's wild game to receive the blessing.

In Genesis 27:25, Isaac eats 'his son's game' before blessing — directly fulfilling the dynamic of Isaac's preference for game that Rebekah and Jacob exploit.

In Genesis 27:31, Esau also prepares game for Isaac, hoping to receive the blessing — reflecting the same preference for game that Isaac had toward Esau.

In Genesis 27:14, Rebekah prepares the savory dish herself — she knows Isaac loves Esau's wild game and uses this knowledge to secure Jacob's blessing.

In Genesis 48:19, Jacob crosses his hands to bless the younger Ephraim over Manasseh — echoing the pattern where the younger is unexpectedly favored.
