After assuaging God’s wrath and ending the plague, Pinchas is hailed:
פִּינְחָס בֶּן אֶלְעָזָר בֶּן אַהֲרֹן הַכֹּהֵן הֵשִׁיב אֶת חֲמָתִי מֵעַל בְּנֵי יִשְׂרָאֵל בְּקַנְאוֹ אֶת קִנְאָתִי בְּתוֹכָם וְלֹא כִלִּיתִי אֶת בְּנֵי יִשְׂרָאֵל בְּקִנְאָתִי – Pinchas, son of Elazar, son of Ahron HaKohen, has turned My anger away from the children of Israel with his zealously avenging Me among them, so that I did not destroy the children of Israel because of My zeal. (25:11)
Rashi notes that his ancestry is traced to his grandfather, which is unusual. People were and are normally identified as their father’s son. This is an exception as people mocked him taking action against Zimri, saying his mother’s father, Yisro, had been a pagan idol worshipper; so the Torah identifies him as being of good stock.
R’ Yonasan Eibshutz wonders what there was to mock. After the fact, the plague stopped and he was hailed as a hero, but even before taking action, no doubt any lucid person would identify that Zimri was liable to the death penalty. So why mock him?
R’ Eibshutz answers that they accepted that Zimri was guilty, but did not kill him themselves because they believed a simple person had to do it; they held themselves too great to carry out the execution. Their mockery was that the idolator’s offspring could!
The Torah identifies his heritage to Ahron – he actually was great. Their reasoning was simply an excuse. When circumstances call for action, someone has to stand up and be counted.
The opening of Yirmiyahu perfectly illustrates this:
וָאֹמַר אֲהָהּ ה’ הִנֵּה לֹא-יָדַעְתִּי דַּבֵּר כִּי-נַעַר אָנֹכִי. וַיֹּאמֶר ה אֵלַי אַל-תֹּאמַר נַעַר אָנֹכִי כִּי עַל-כָּל-אֲשֶׁר אֶשְׁלָחֲךָ תֵּלֵךְ וְאֵת כָּל-אֲשֶׁר אֲצַוְּךָ תְּדַבֵּר – I said, “Alas, God! Behold, I do not know how to speak, for I am just a kid!” And the Lord said to me; “Do not say to me Me “I am just a kid,” because wherever I send you, you will go, and whatever I command you, you will say”. (1:6-7)
R Nosson Vachtvogel remarked how many great people fell by the wayside by not internalizing אַל-תֹּאמַר נַעַר אָנֹכִי. The Gemara teaches that every individual must walk through life believing that the entire universe was created exclusively for their sake.
There is a time and place for everything; there is a time to be humble and keep your opinion to yourself; but there may be a time to stand up and change the world. It’s as simple as recognizing an issue, and being ready to something about it.
