[19] "I am Esau thy firstborn": St. Augustine (L. Contra mendacium, c. 10), treating at large upon this place, excuseth Jacob from a lie, because this whole passage was mysterious, as relating to the preference which was afterwards to be given to the Gentiles before the carnal Jews, which Jacob by prophetic light might understand. So far is certain, that the first birthright, both by divine election and by Esau's free cession belonged to Jacob: so that if there were any lie in the case, it could be no more than an officious and venial one.
[36] "Jacob": That is, a supplanter.
