And when Rebecca had heard this, and he was gone into the field to fulfill his father's commandment,

And Rebecca heard when Isaac spoke to Esau his son. And Esau went to the field to hunt venison, to bring it.

And Rebekah is hearkening while Isaac is speaking unto Esau his son; and Esau goeth to the field to hunt provision, to bring in;

Now Isaac's words to his son were said in Rebekah's hearing. Then Esau went out to get the meat.

Rebekah heard when Isaac spoke to Esau his son. Esau went to the field to hunt for game, and to bring it.

And when Rebekah had heard this, and he had gone out into the field to fulfill his father's order,

Ribca autem audiebat, dum loqueretur Ishac ad Esau filium suum: et perrexit Esau in agrum, ut venaretur venationem, ut afferret.

And Rebekah heard. Moses now explains more fully the artifice by which Jacob attained the blessing. It truly appears ridiculous, that an old man, deceived by the cunning of his wife, should, through ignorance and error, have given utterance to what was contrary to his wish. And surely the stratagem of Rebekah was not without fault; for although she could not guide her husband by salutary counsel, yet it was not a legitimate method of acting, to circumvent him by such deceit. For, as a lie is in itself culpable, she sinned more grievously still in this, that she desired to sport in a sacred matter with such wiles. She knew that the decree by which Jacob had been elected and adopted was immutable; why then does she not patiently wait till God shall confirm it in fact, and shall show that what he had once pronounced from heaven is certain? Therefore, she darkens the celestial oracle by her lie, and abolishes, as far as she was able, the grace promised to her son. Now, if we consider farther, whence arose this great desire to bestir herself; her extraordinary faith will on the other hand appear. For, as she did not hesitate to provoke her husband against herself, to light up implacable enmity between the brothers, to expose her beloved son Jacob to the danger of immediate death, and to disturb the whole family; this certainly flowed from no other source than her faith. [1] The inheritance promised by God was firmly fixed in her mind; she knew that it was decreed to her son Jacob. And therefore, relying upon the covenant of God, and keeping in mind the oracle received, she forgets the world. Thus, we see, that her faith was mixed with an unjust and immoderate zeal. This is to be carefully observed, in order that we may understand that a pure and distinct knowledge does not always so illuminate the minds of the pious as to cause them to be governed, in all their actions, by the Holy Spirit, but that the little light which shows them their path is enveloped in various clouds of ignorance and error; so that while they hold a right course, and are tending towards the goal, they yet occasionally slide. Finally, both in Isaac and in his wife the principle of faith was preeminent. But each, by ignorance in certain particulars, and by other faults, either diverged a little from the way, or, at least, stumbled in the way. But seeing that, nevertheless, the election of God stood firm; nay, that he even executed his design through the deceit of a woman, he vindicates, in this manner, the whole praise of his benediction to his own gratuitous goodness.

1 - This is a dangerous position, however it may be modified or explained. True faith never leads to sin. It was the mixture, not to say the predominance of unbelief, which caused Rebekah, instead of waiting for the fulfillment of God's promises in his own way, to plot and to execute a scheme of imposture, which involved herself and her family in perpetual disquietude. What Calvin calls zeal, he ought to have called rashness and something worse. -- Ed.

And Rebekah heard - And was determined, if possible, to frustrate the design of Isaac, and procure the blessing for her favorite son. Some pretend that she received a Divine inspiration to the purpose; but if she had she needed not to have recourse to deceit, to help forward the accomplishment. Isaac, on being informed, would have had too much piety not to prefer the will of his Maker to his own partiality for his eldest son; but Rebekah had nothing of the kind to plead, and therefore had recourse to the most exceptionable means to accomplish her ends.

And Rebekah heard when Isaac spake to Esau his son,.... She might hear Isaac call to him by one means or another, that he had sent for him, or might see him go into his father's tent, and might stand at the door of it and listen to hear what he said to him; though the Targum of Jonathan says, she heard by the Holy Spirit:
and Esau went to the field to hunt for venison, and to bring it; as his father directed and enjoined him; and thus it was ordered by divine Providence, that there might be time and opportunity for Jacob to get the blessing before his broker.

Rebekah, who heard what he said, sought to frustrate this intention, and to secure the blessing for her (favourite) son Jacob. Whilst Esau was away hunting, she told Jacob to take his father a dish, which she would prepare from two kids according to his taste; and, having introduced himself as Esau, to ask for the blessing "before Jehovah." Jacob's objection, that the father would know him by his smooth skin, and so, instead of blessing him, might pronounce a curse upon him as a mocker, i.e., one who was trifling with his blind father, she silenced by saying, that she would take the curse upon herself. She evidently relied upon the word of promise, and thought that she ought to do her part to secure its fulfilment by directing the father's blessing to Jacob; and to this end she thought any means allowable. Consequently she was so assured of the success of her stratagem as to have no fear of the possibility of a curse. Jacob then acceded to her plan, and fetched the goats. Rebekah prepared them according to her husband's taste; and having told Jacob to put on Esau's best clothes which were with her in the dwelling (the tent, not the house), she covered his hands and the smooth (i.e., the smoother parts) of his neck with the skins of the kids of the goats,
(Note: We must not think of our European goats, whose skins would be quite unsuitable for any such deception. "It is the camel-goat of the East, whose black, silk-like hair was used even by the Romans as a substitute for human hair. Martial xii. 46." - Tuch on v. 16.)
and sent him with the savoury dish to his father.
