Bereishis/Toldos - Eating Tzaid

In parsha Toldos, we read that

 וַיֶּאֱהַ֥ב יִצְחָ֛ק אֶת־עֵשָׂ֖ו כִּי־צַ֣יִד בְּפִ֑יו וְרִבְקָ֖ה אֹהֶ֥בֶת אֶֽת־יַעֲקֹֽב

And Isaac loved Eisav, because of  trapped meat (צַ֣יִד - tzaid)  in his mouth, while Rivkah loved Yaakov. ( Bereishit 25:28)

Rashi explains:

בפיו. כְּתַרְגּוּמוֹ בְּפִיו שֶׁל יִצְחָק. וּמִדְרָשׁוֹ בְּפִיו שֶׁל עֵשָׂו, שֶׁהָיָה צָד אוֹתוֹ וּמְרַמֵּהוּ בִדְבָרָיו:

As the Targum renders it: in Isaac’s mouth (i.e. Isaac ate the trapped meat he brought home). But its Midrashic explanation is: there was hunting ( צַ֣יִד - tzaid)   in Eisav's  mouth, meaning that he used to entrap and deceive him by his words (Genesis Rabbah 63:10).

Question: How can a tzaddik such as Isaac be entrapped and fooled by Eisav with a piece of meat (tzaid)? The Midrash says that Eisav would ask questions about tithing salt and straw every time he came into the house of Isaac. Can a tzaddik really be fooled by such repeated questions, and wouldn't it raise suspicion in Isaac's mind that the question had already been asked on numerous occasions, and its repetition implies low IQ on the part of the questioner? Doesn't Isaac have any more noble and worthy reasons to love Eisav over Yaakov besides hearing daily the same silly questions about tithing salt and straw while eating trapped tzaid?

On a superficial level this is difficult to understand, but if we look deeper we find that yes indeed, there was a profound reason to love Eisav more than Yaakov. The key in solving this puzzle is by interpreting the phrase " eating tzaid" metaphorically, where eating ( ohal) means destroying as in

 יֹאכַ֞ל גּוֹיִ֣ם צָרָ֗יו וְעַצְמֹתֵיהֶ֛ם יְגָרֵ֖ם וְחִצָּ֥יו יִמְחָֽץ

They shall devour ( eat - ohal) enemy nations, crush their bones, and smash their arrows. (Numbers 24:8)

and tzaid ( trapping) is interpreted as king Nimrod 

הֽוּא־הָיָ֥ה גִבֹּֽר־צַ֖יִד לִפְנֵ֣י יְהֹוָ֑ה עַל־כֵּן֙ יֵֽאָמַ֔ר כְּנִמְרֹ֛ד גִּבּ֥וֹר צַ֖יִד לִפְנֵ֥י יְהֹוָֽה׃

He ( Nimrod) was a mighty entrapper ( tzaid) before Hashem, therefore it is said "As Nimrod, a mighty entrapper ( tzaid) before Hashem" (Genesis 10:9)

Therefore, Isaac eating tzaid means destroying Nimrod, Israel's arch enemy at the time, and bringing tzaid to Yaakov, is understood as his bringing the news about Nimrod to Isaac, which they consumed, i.e. discussed daily, in order to plan his destruction. We also see that Eisav was Nimrod's match, as he too is called one who knows hunting and trapping.

וַֽיִּגְדְּלוּ֙ הַנְּעָרִ֔ים וַיְהִ֣י עֵשָׂ֗ו אִ֛ישׁ יֹדֵ֥עַ צַ֖יִד אִ֣ישׁ שָׂדֶ֑ה וְיַעֲקֹב֙ אִ֣ישׁ תָּ֔ם יֹשֵׁ֖ב אֹהָלִֽים׃

When the boys grew up, Esau became one who knows hunting ( tzaid), a man of the field; but  Yaakov was a pure  man, living in tents. (Genesis 25:27)

This supports the notion that Yaakov's love for Eisav was grounded in the belief that Eisav is a mighty hunter, a warrior, Nimrod's fearsome match, and a prototype of David, who was also red, just like Eisav, as it says:

וַיִּשְׁלַ֥ח וַיִּבְאֶ֖הוּ וְה֣וּא אָ֑דֶם עִם־יְפֵ֥י עֵ֖ין וְטֽוֹב־רֹֽאִי וַיֹּֽאמֶר־יְהוָ֤ה קֽוּם־מַשְׁחֵ֣הוּ כִּֽי־זֶ֥ה הוּא

So he sent and brought him in. Now he (David) was red, with beautiful eyes and a good-looking appearance. And the Lord said, 'Arise, anoint him; for this is the one!' (1 Samuel 16:12)

Yaakov therefore loved Eisav, because he believed that he is destined for war and greatness, just like David, whose name is spelled  דָּוִד which has the same letters as the word דּוֹד, dod, which means beloved.  Thus, Eisav was worthy of love, just like David. He believed that Eisav would avenge Nimrod's killing of Haran, Avraham's brother, and drive Cnaan invaders from the Promised Land. 

Yet, Isaac was deceived, because even though he was potentially as great as David, he was in it for himself, and his goal was not to defeat Nimrod and his 4 empires (Babel, Erech, Accad, and Calneh - Genesis 10:10-12) in order to bring about the knowledge of God and establish the Kingdom of Heaven  upon earth, as Avraham and Isaac were commanded to do, but to build a rebellious, cruel and corrupt empire of his own, which eventually became known as Rome. This was his deception and entrapment that he put into Isaac's mouth.
