And he said, Behold now, I am old, I know not the day of my death:Now therefore take, I pray thee, thy weapons, thy quiver and thy bow, and go out to the field, and take me some venison;And make me savoury meat, such as I love, and bring it to me, that I may eat; that my soul may bless thee before I die. Genesis 27:2-4

Well were coming to the end of Isaacs life. And Isaac wants to bless his firstborn son, which was tradition back then. Esau was technically the firstborn son even though him and Jacob were paternal twins. However if you remember a few chapters back, Esau sold his birthright to Jacob for a bowl of stew

So Esau still thinks hes going to get the blessing, even though he sold his birthright. So he goes out hunting per his fathers request to find him a deer for his final meal. Meanwhile their mother, Rebekah devices a plan for Jacob to trick his father into getting the blessing. This is one of the reasons Jacob has become known as a “deceiver”

More background is the Bible tells us Esau was actually his fathers favorite because he was a mighty hunter however Jacob was his mothers favorite because he was quiet and liked to hang around the house (Genesis 25:27-28)

And Jacob said unto his father, I am Esau thy firstborn; I have done according as thou badest me: arise, I pray thee, sit and eat of my venison, that thy soul may bless me. Genesis 27:19

Jacob went ahead with the plan that him and his mother came up with to deceive his father. Esau was a hairy man and Jacob wasn’t, so he wore animal fur to discuss himself. His father was surprised he found a deer so quickly, but he believed his son and ate it anyway

Therefore God give thee of the dew of heaven, and the fatness of the earth, and plenty of corn and wine: Let people serve thee, and nations bow down to thee: be lord over thy brethren, and let thy mother’s sons bow down to thee: cursed be every one that curseth thee, and blessed be he that blesseth thee. Genesis 27:29-30

Isaac blessed his son, who he thought was Esau but was really Jacob. Esau arrived right after his father finished blessing Jacob. Obviously his father was greatly confused when Esau brought back a deer at his request.

And he said, Thy brother came with subtilty, and hath taken away thy blessing. Genesis 27:35

Eventually Isaac realized he blessed the wrong son but it was too late. Esau begged for a blessing but his father said Esau will serve Jacob. Obviously this angered Esau greatly and vowed to kill Jacob when he finds him.. This fulfilled the prophecy of two nations coming from Rebekah’s womb (Genesis 25:23) His mother sent Jacob away to hide so Esau doesn’t kill him

Esau would eventually form the nation of Edom, which would be longtime enemies of Israel for years to come!
