And Jacob said, Swear to me this day; and he sware unto him: and he sold his birthright unto Jacob.
Ver. 33. Swear to me.] With fickle men, make all firm and fast.
“Quo teneam vultus mutantem Protea nodo?” - Horat.
And he sold his birthright to Jacob.] And, with it, heaven also, as the Jerusalem Paraphrast addeth, whereof the birthright was a type and pledge. So his sin was in unthankfulness for such a dignity; in limiting it to this life; in selling it so very cheap; but especially, in his profane parting with a spiritual blessing for a temporal. Such a foolish bargain makes every impenitent person in the sale of his soul for a thing of nought; which Christ, who only went to the price of a soul, saith is more worth than a world. "Let there be no fornicator," as every worldling is, Jam 4:4 "or profane person among us, as Esau". Heb 12:16 And that there may not, let not men take pleasure in pleasure, spend too much time in it, shoot their affections too far into it. It is no wisdom, to go as far as we may. It was not simply a sin in Esau to go a hunting: but yet the more he used it the more profane he grew by it, and came at length to condemn his birthright. Adrian a the emperor was a great hunter; broke his leg in hunting; called a city that he built in Mysia, by the name of Adrian's huntings: but how little care he took for his poor soul, that Animula vagula blandula of his, abundantly testifieth. The maddest hunter that ever I read of was Mithridates; who was so set upon it, that he came not into any house, either of city or country for seven years together. b To lawful delights and recreations, God allows men to stoop, for their bodies' sake; as the eagle to the prey, or as Gideon's soldiers, to soop their handful, not to gorge their bellyful. An honest man's heart is where his calling is: such a one, when he is elsewhere, is like a fish in the air, whereunto if it leap for recreation or necessity, yet it soon returns to its own element.
