What does Genesis 27:10 mean?
Isaac's wife, Rebekah, has overheard his plan to bless their firstborn son, Esau (Genesis 27:1–6). However, Rebekah greatly prefers the younger of the twin boys, Jacob (Genesis 25:28). Isaac might have been trying to avoid this very situation by speaking to Esau alone, rather than stating his blessing in front of the entire family. Rebekah knows that God has predicted that Jacob, not Esau, will be superior (Genesis 25:23). In an effort to "help" God's plans along, and to aid her favored son, she hatches a deceptive plot (Genesis 27:7–9).Here, Rebekah concludes describing to Jacob her plan for him to receive the family blessing from Isaac instead of Esau. This relies heavily on Isaac's age-induced blindness. Before Esau can return with freshly hunted game and prepare it as a delicious meal, she will prepare a meal herself. Then Jacob can take it to his father and receive the blessing instead.
Jacob will raise very reasonable objections to his mother's plan in the following verses. Readers should note that his concerns are about being caught—not whether or not this is a moral plan (Genesis 27:12).
