In Ezra 5-6 appears the governor of Ever Hanahar (the southern side of the Euphrates in this case), Tattenai. Tattenai, upon seeing that the Jews got back to building the Temple after several years of not being able to, asks what they're doing and who gave them permission to do so? They answer that they received permission in the time of Koresh. He tells them that he's going to check it out, but meanwhile they can continue their work. After the proper document is discovered in the Median archives and new documents are commissioned by King Daryavesh, he passes these on to the Jews and doesn't appear again. For all intents and purposes, he seems to have only been doing his job as government official. Nothing bad about checking building permits, right? Moreover, Tattenai even let them continue working while he sorted though the bureaucracy (and considering that the main archives were in Babylon but the document was found in Media, it was quite some bureaucratic mess).
Targum Yonatan, however, seemed to have viewed him negatively, as he wrote on Ester 5:10-11:
"וְאִזְדְרִיז הָמָן וְעַל לְבֵיתֵיהּ וּשְׁדַר וּקְרָא יַת רְחִימוֹי וְיַת זֶרֶשׁ רַשִׁיעֲתָא אִנְתְּתֵיהּ בְּרַת תַּתְּנַי פַּחַת עֵבֶר נַהֲרָא: וְאִשְׁתָּעֵי לְהוֹן הָמָן יַת יְקָר עָתְרֵיהּ וְהֵיךְ אִתְמַנֵי עִם דוּכְסֵי מַלְכָּא וְהֵיךְ רָהֲטִין קֳדָמוֹי סְגִיאוּת בְּנוֹי דִסְכוֹמְהוֹן מָאתָן וּתְמַנְיָא בַּר מִן עֲסַרְתֵּי אוֹחֲרָנִין דְאִנוּן פּוּלְמַרְכִין עַל פַּלְכַיָא וּבַר מִן שַׁמְשַׁי דְהוּא סַפְרָנָא דְמַלְכָּא..."
Translation: "And Haman hurried and went to his home and he sent and called his friends and the evil Zeresh his wife, duaghter of Tattenai the governor of Ever Hanahar. And Haman told them all of the great things that happaned to him and how he was chosen to be among the lords of the king and how before him run many sons who amount to 208 besides for the last ten who are governors of provinces and besides Shamshai who is a scribe of the king..."
According to the Targum, Tattenai was the father of Zeresh, father-in-law of Haman and grandfather (or at least, step-grandfather) of Haman's children, including Shamshai, who was one of the leaders of Tzarei Yehudah who brought about the cessation of the building of the Temple prior to Ezra ch. 5. It seems that the Targum viewed Tattenai negatively, which makes me wonder why. I saw nothing problematic with what he did; it was actually in stark contrast to what his grandson Shamshai did (with regards to the Jews in Judea). It occurred to me that the Targum may be emphasizing the differences between the different generations of the family, but Rabbi Yosef ibn Yachiya wrote on Ester 5:10:
"...והביא אוהביו וזרש אשתו אשר היתה בת תתני פחת עבר הנהר שונא ישראל..."
Translation: "...and he brought his friends and his wife Zeresh who was the daughter of Tattenai the governor of Ever Hanahar the enemy of Yisrael..."
So what did the Targum have against Tattenai? What evil thing did Tattenai do?
