How did hasatan blind so many in Yisro'el?

[JohnD70X7]

Having recently refined my evangelist outreach to benai Yehudiym (particularly yet not exclusively) I have found that the leaven of the Pharisees (which Yeshua called it) which blinds the children of Israel to who and what their Messiah is comes from a laser focus on Torah to the detriment of the purpose of Torah... which was the foundation for the entirety of Tanakh.

Torah Moshe was never the complete Torah Elohiym, but the first phase of the complete Law of God (not by any deficiency in the Law of Moses but in that of human inability to truly keep the Law). And G-d provided phase two for that cause:

Yirimyahu 31: (Chabad Tanakh)

30Behold, days are coming, says the Lord, and I will form a covenant with the house of Israel and with the house of Judah, a new covenant.		להִנֵּ֛ה יָמִ֥ים בָּאִ֖ים נְאֻם־יְהֹוָ֑ה וְכָֽרַתִּ֗י אֶת־בֵּ֧ית יִשְׂרָאֵ֛ל וְאֶת־בֵּ֥ית יְהוּדָ֖ה בְּרִ֥ית חֲדָשָֽׁה:
31Not like the covenant that I formed with their forefathers on the day I took them by the hand to take them out of the land of Egypt, that they broke My covenant, although I was a lord over them, says the Lord.		לאלֹ֣א כַבְּרִ֗ית אֲשֶׁ֚ר כָּרַ֙תִּי֙ אֶת־אֲבוֹתָ֔ם בְּיוֹם֙ הֶֽחֱזִיקִ֣י בְיָדָ֔ם לְהֽוֹצִיאָ֖ם מֵאֶ֖רֶץ מִצְרָ֑יִם אֲשֶׁר־הֵ֜מָּה הֵפֵ֣רוּ אֶת־בְּרִיתִ֗י וְאָֽנֹכִ֛י בָּעַ֥לְתִּי בָ֖ם נְאֻם־יְהֹוָֽה:
32For this is the covenant that I will form with the house of Israel after those days, says the Lord: I will place My law in their midst and I will inscribe it upon their hearts, and I will be their God and they shall be My people.		לבכִּ֣י זֹ֣את הַבְּרִ֡ית אֲשֶׁ֣ר אֶכְרֹת֩ אֶת־בֵּ֨ית יִשְׂרָאֵ֜ל אַֽחֲרֵ֨י הַיָּמִ֚ים הָהֵם֙ נְאֻם־יְהֹוָ֔ה נָתַ֚תִּי אֶת־תּֽוֹרָתִי֙ בְּקִרְבָּ֔ם וְעַל־לִבָּ֖ם אֶכְתֳּבֶ֑נָּה וְהָיִ֚יתִי לָהֶם֙ לֵֽאלֹהִ֔ים וְהֵ֖מָּה יִֽהְיוּ־לִ֥י לְעָֽם:
33And no longer shall one teach his neighbor or [shall] one [teach] his brother, saying, "Know the Lord," for they shall all know Me from their smallest to their greatest, says the Lord, for I will forgive their iniquity and their sin I will no longer remember.		לגוְלֹ֧א יְלַמְּד֣וּ ע֗וֹד אִ֣ישׁ אֶת־רֵעֵ֜הוּ וְאִ֚ישׁ אֶת־אָחִיו֙ לֵאמֹ֔ר דְּע֖וּ אֶת־יְהֹוָ֑ה כִּֽי־כוּלָּם֩ יֵֽדְע֨וּ אוֹתִ֜י לְמִקְּטַנָּ֚ם וְעַד־גְּדוֹלָם֙ נְאֻם־יְהֹוָ֔ה כִּ֚י אֶסְלַח֙ לַֽעֲו‍ֹנָ֔ם וּלְחַטָּאתָ֖ם לֹ֥א אֶזְכָּר־עֽוֹד:

The blindness of Israel to this and Yeshayahu 52:13 - 53:12 (the suffering servant Yeshua) is the over zealous focus on only Torah.
