In today’s Chumash, Yaakov gets the brachos, and needs to run away when Eisav finds out.
Yaakov’s brachos: Yitzchak Avinu thought that Yaakov was really Eisav! He gave him ten brachos!
Some of the brachos are that he should have rain, so his food will grow well. He should rule other nations and other nations should not rule over him! People who curse him should be cursed, and people who give him brachos should get brachos too. We read these brachos at the beginning of Veyitein Lecha, that we say on Motzei Shabbos!
Eisav’s brachos: After getting the brachos, Yaakov left. Just then, Eisav came back with the food he prepared. He told Yitzchak to come eat, so he could get the brachos.
“Who are you?” Yitzchak asked.
“I am your oldest son, Eisav,” he answered.
When Yitzchak heard this, he was very confused. He also saw Gehennom opening in front of Eisav, and he started to shake! “So who brought me food before? I gave the brachos to him already! But I see he deserved the brachos, so he will keep them.”
Eisav was very upset! He screamed, “Give me a bracha too!”
“But I already gave your brachos to Yaakov — he came in a tricky way and I thought it was you.”
“So that’s why you called him Yaakov!” Eisav cried. “Yaakov can mean to trap — and he already trapped me twice! First, he took away the bechorah from me (the zechus and responsibility of being the oldest), and now he also took my bracha!”
Now Yitzchak saw that this wasn’t a mistake at all! Eisav sold his bechorah, so Yaakov really DID deserve to get the brachos for the oldest! He told Eisav that Yaakov had a bracha now to rule over him, but Eisav still cried that he wanted a bracha too.
Yitzchak gave Eisav a bracha that he would have rain so his plants will grow, even if he didn’t deserve it. And if he would see Yaakov’s children (the Yidden) doing aveiros, he would be allowed to rule over them until they do Teshuvah.
Yaakov runs away: Eisav was very angry at Yaakov! Because of Yaakov, he got a less special bracha! Eisav wanted to kill Yaakov, but he decided to wait until Yitzchak passed away, so he wouldn’t make his father upset.
Rivkah knew about Eisav’s plan through Ruach Hakodesh, and warned Yaakov to run away. She told him to go to Lavan’s house in Charan, and stay there until Eisav isn’t angry anymore. “I will send you a message when you can come home,” she told him. “Don’t try to fight Eisav, because then his children will try to kill you.”
Rivkah wanted Yaakov to have even more brachos. She told Yitzchak that she was worried that Yaakov would marry a Chiti girl like Eisav. So Yitzchak gave Yaakov a bracha to go find a wife from Rivkah’s family in Padan Aram, and that many children should come from him. He gave him many of the brachos that Hashem gave to Avraham Avinu, and a bracha that Eretz Yisrael will belong to HIS children, not Eisav’s!
