What does, קַח לְךָ, take for yourself, mean? Rashi explains, קָחֶנּוּ בִּדְבָרִים , take him with words. Draw him in convince him and say to him, אַשְׁרֶךָ שֶׁזָּכִיתָ לְהַנְהִיג בָּנָיו שֶׁל מָקוֹם, fortunate are you that you are zocheh to be manhig the children of Hashem.
The Torah relates an episode that took place in the midbar where a nasi of Shevet Shimon faced a tremendous challenge and he publicly did an act that shouldn’t have been done. We have to understand that he did it with a cheshbon. It wasn’t that he just fell into a ta’avah. You have to know this man, Zimri, was 250 years old. He was past the ta’avah stage. But Pinchas came along and took his life. Pinchas performed a ma’aseh kanaus, an act of zealotry and he speared them both with a spear.
