What does Genesis 27:25 mean?
Isaac has attempted to privately pass along his fatherly blessing to Esau, the oldest of his twin sons. He requested Esau to bring him his favorite food, so that he could bestow this gift (Genesis 27:1–5). However, Isaac's wife, Rebekah, overheard the plan and conspired with her favorite of the twins, Jacob, to steal the blessing (Genesis 27:6–10). This elaborate scam involved disguising Jacob so that the elderly, blind Isaac would think he was speaking to the other brother (Genesis 27:11–17).Though Isaac never seems fully convinced that the son in front of him is Esau (Genesis 27:21–23), he finally decides to eat the meal brought for him. For Isaac, eating this meal and giving the blessing are linked. Together, they are part of a meaningful ceremony. Isaac requests that his son's game be brought to him, still suggesting that he may suspect he is not speaking to the right son.
Still, Isaac eats and drinks what Jacob gives to him. The blessing will follow.
