Parshas Toldas

The world knew that there is a set of twins growing up in the house of Yitzchok that were vastly different. Yaakov was אִישׁ תָּם יֹשֵׁב אֹהָלִים, while Esav was אִישׁ יֹדֵעַ צַיִד אִישׁ שָׂדֶה. It was quite obvious that yakov would be the bearer of the mesora handed down from Avraham. It was clear to all - except to Yitzchok. וַיֶּאֱהַב יִצְחָק אֶת-עֵשָׂו כִּי-צַיִד בְּפִיו. Yitzchok was apparently fooled by Esavs behavior not just did he love him but he also wanted to bestow the brochas on Esav before he died. How do we understand that Yitzchok was shortsighted and didn’t see the faults of his son? Why did he want to give the brochas to Esav over Yakov?
The example we are given of how Esav fooled Yitzchok is that he would ask ‘how does one tithe salt?’ Is their any significance to this question or is it just a random example of the kind of questions Esav would ask?
There is a partnership known to Jews as 'Yissoschar - Zevulan' partnership. The people of Yissoschar were known to be the greatest Torah scholars- they toiled in the Torah all day. Who was to support them? Where would they have the money to live on? The answer is in the tribe which neighbored them. The people of Zevulan were tradesmen. The piece of land that they were allotted was strategically situated near the port - they made their fortune by trading. But what would be of their Torah learning? If they worked all day when would they learn? Zevulan was to support Yissoschor, it was to be a fifty- fifty partnership. Half the money that the people of Zevulan profited in their trade was to go to the people of Yissoschor as means of support. In return the people of Zevulan received half of the Torah learning done by the people of Yissoschor. When Yaakov and Moshe- respectively - blessed Klal Yisroel before their deaths they both blessed Zevulan before Yissaschor. They made the point to teach us that both of the partners had an equal share in the learning of Yissoschar. Both the learners and the supporters would share the reward.
The Imrai Noam (R’ Mier of Dzikev) explains; Yitzchok was not fooled by Esav – he knew exactly what his strengths were. He realized that Yaakov and Esav had two different personalities, that Yaakov was the studious type while Esav was a man of the fields. Yitzchok envisioned a world where these two opposite personalities would come together and form one group. His hope was for Esav and Yaakov to build a Yissoschar – Zevulan type of relationship. It would be the only way for Esav to lead a fulfilling life. Esav would go out and make the money supporting Yaakov who would sit and learn torah- bringing ultimate harmony to the world, and both Yaakov and Esav would share the reward. It is precisely in this respect where Esav fooled his father. He wanted to know the exact halachos of masser and tzedaka, he tried to impress upon – and succeeded in fooling - Yitzchok that he was fulfilling his part of the deal, he was ready to give tzedakah even from salt in order to support Yaakov.
The Brochos of Yitzchok were blessings of an abundance of wealth – the pleasures of this world. Yitzchok wanted to give Esav the wealth and that he should share it with Yaakov leaving him free to spend his days learning- thus giving Esav a part of the world to come.
P.S. It is worthwhile to read R’ Shamshan Refoel’s essay on Yaakov and Esav in Collected Writings volume 7. He explains the two personalities of Yaakov and Esav as we did.
