Matthew Poole and continuators on Genesis 25:33

33 And Jacob said, swear to me this day , and he sware unto him, and he sold his birth-right unto Jacob.

Iacob acted subtilly in this affair, he knew that delays were dangerous, and Esaus consideration or second thoughts might have spoiled his bargain, and therefore herequires haste as in the sale, so in his Oath, wherein he addeth another sin, in hurrying his brother into an Oath by precipitation, which neither his brother should have taken, nor Iacob should have advised him to take, without mature advice.
