Genesis 27:1
1When Isaac was old, and his eyes were dim, so that he could not see, he called Esau his elder son, and said to him, “My son?” He said to him, “Here I am.”
Isaac is old, eyes dim, and he calls Esau “his elder son.” Favoritism chooses the audience before the blessing is spoken.
What comes through is a responsible preference. Blindness does not annul agency: the father summons the son he loves, not the son the oracle named (25:23).
Age and dim sight set the scene, yet the first move is Isaac’s call to Esau. The household already leans (25:28).
Reformed readers remember that God’s purpose according to election stands behind this mess. Providence will overrule the father’s favoring without making that favoring holy.
