Genesis 27

1 Isaac was blind in his old age.
2 Isaac thought he would die soon, and he wanted to get his affairs in order.
3 As a last request, Isaac wanted to have his favorite dish made by his favorite son.
4 Isaac may not have been able to taste much either, and asked for a spicy dish that would have some flavor. Isaac promised that this meal would be a prelude to receiving the blessing. Esau had already lost his physical inheritance, but Isaac could still give him the spiritual inheritance: the promises that God gave to Abraham.
5 Rebekah may have been in the tent attending to Isaac or she might have been eavesdropping.
6 Rebekah wanted her favorite son to have the blessing, so she was about to hatch a plot to obtain it for him. What Rebekah appears to forget is that God already promised that Jacob would receive the blessing. Rebekah did not need to "help" God do what He promised. As we will see, when people interfere with God's plan, it causes problems. God does use her efforts, but it would have worked out better if Rebekah had let God determine how it should happen.
9 Jacob did not know how to hunt like his brother, but Rebekah thought that she could mimic Esau's recipe for spicy game. Again, if Isaac could not taste well, he would not have noticed the difference between game and domestic meat.
11 Jacob did not object because this would be a wrong thing to do, he objected because it was certain that he would be caught. Parents have an important responsibility in teaching their children about God and His moral standards.
12 A curse would be devastating. We do not take such parental blessings and curses seriously any more. Often today parents bless and curse without thinking. In the Bible, God often honors these things, and He probably still honors many of them today. This does not mean that God will not overrule.
13 This may be a meaningless statement, since curses are not necessarily transferable. However, we do have the one example of Jesus. As sinners, we humans fall under the curse of decay and death. Even worse, we fall under the curse of being separated from God. However, our curse was transferred to Jesus on the cross. We are only required to obey the voice of God. Here Rebekah was asking Jacob to obey her voice, not God's.
17 Rebekah took care of the food, clothing, and hairy skin. The rest of the deception was up to Jacob.
18 This could have been a common question for Isaac since he was unable to see. However, it is more likely that Jacob was trying to disguise his voice. The result was a voice that Isaac was unfamiliar with so he asks for clarification.
19 Jacob is quite the bold liar here.
20 Isaac felt that something was not quite right. Sometimes out gut feelings are right, but often it is wise to get more information. Here, Isaac does gather more information, but in the end, he is still deceived. Sometimes research will not lead us to correct conclusions. Some deceivers will take advantage of the fact that we can not gather all the information we need before we make a decision.
21 Isaac is very open about his skepticism. Isaac reasoned that someone could try to disguise his voice, but would be unable to change his physical characteristics.
22 Jacob remains calm and grants his father's request. He could have backed down and confessed, but at this point he was certain to receive a curse rather than a blessing.

Jacob probably looked ridicules with goatskins tied to various parts of his body, but to Isaac they felt like the thick hair of Esau.

24 As the final confirmation, Isaac relies on the "honesty" of his sons. If we have questions about something, it is sometimes best to ask about it directly. There are times when we can only trust someone at his word. This leaves us open to deceit, but we know at that point that the wrong was done by the other person.
27 At this point Jacob seems to be paralleling Judas. He is in the midst of deception (a betrayal of trust) even while he is pretending to be loving and caring.

The clothing, food, hairy attributes, and the verbal confirmation all pointed to Esau. Only the voice and the timing indicated that something was not right. However, with this final piece of evidence Isaac is convinced that it is indeed Esau presents and proceeds with the blessing.

28 Isaac's blessing included ample water, success in livestock (or hunting), and success in farming.
29 The blessing also included the right to be leader of the family, and the hope of being a leader over other people. Even above that, are the blessings others would receive by accepting him, and the curses others would receive by rejecting him.
30 If Jacob had taken another few minutes, a more awkward situation would have occurred.
31 Esau was unaware of the caper and prepared a meal, just as his father asked.
32 This time Isaac is confused. He had earlier convinced himself that Jacob was Esau. Now he does not know what to do when the real Esau shows up.
33 Isaac was very upset when he figured out that he had been tricked. The blessing was the most important thing he could do before he died. Isaac intended it for Esau, but now someone else had it. The blessing was irrevocable and non-transferable, even if it was mistakenly given to the wrong person.
34 After selling his birthright, Esau may have gained an appreciation for the blessing, because that was the only thing left for him to inherit. He may have come to understand that the blessing was more important than the physical inheritance.
36 Jacob, which can mean "trickster," had both the physical and spiritual inheritance because he took advantage of Esau and deceived his father. Esau now asks for any leftover blessings.
37 Isaac had intended to give everything to Esau and leave nothing for Jacob. This may seem harsh, but God's promise to Abraham could not be split. It had to go to either one or the other. The tables were turned, and since Isaac had mistakenly given all his wealth and power to Jacob and left nothing for Esau.
38 Esau is devastated. He began to cry and begged for even a single blessing.
39 Esau's blessing was not much of a blessing. He would continue to be a hunter and a warrior. Eventually he would revolt against his brother.
41 The unnecessary trickery brought about unnecessary strife between the brothers.

Anger leads to hatred, and hatred leads to murder. Cain killed his brother, Abel, in a calculated manner and Esau planed to kill Jacob during or after the customary mourning period. Out of respect to his father, he intended to wait until Isaac died.

42 Rebekah, being the eyes and ears of the family, soon found out about the plot against Jacob.
43 God told Isaac not to return to his ancestral homeland. Here, Rebekah's voice told Jacob to do so.
44 These "few days" would become 20 years (Gen 31:38). Rebekah would never see her favorite son again.
45 If Esau murdered Jacob, the custom of vengeance required the nearest relative to execute Esau. Thus, Rebekah would lose both of her sons shortly after her husband died.
46 Rebekah hatched another plot to get Jacob away from Esau. Esau's wives annoyed Rebekah and Isaac (Gen 26:35), and she used this as an excuse to send Jacob back to her homeland. At least Rebekah made a right choice in preventing Jacob from marrying a Canaanite woman.
