John Chrysostom
Observe the careful nature of sacred Scripture. When Isaac inquired, “Are you my son Esau?” and he replied, “I am,” his father touched him and still felt uncertain, caught in confusion and doubt regarding his voice. He asked again, “Are you my son Esau?” to which he affirmed, “I am,” and presented him with food, and after he ate, it is recorded that he embraced him and bestowed his blessing upon him.
