וַיֹּאמֶר אֲלֵיהֶם מֹשֶׁה הַחִיִּיתֶם כָּל נְקֵבָה
When the soldiers returned with the women they had captured from מדין we find משה quite annoyed. He exclaims in a rhetorical manner, "You let the all the women live?!" A rhetorical question, however, is still a question. The understanding of this statement as a question hinges on the ניקוד of הַחִיִּיתֶם. If this word were to be mispronounced הֶחֶיִֵיתֶם it would lose its interrogative form and be understood as a statement - "You have let all the women live." While the message of the פסוק would ultimately be the same, I think this mistake would distort the true meaning of the word and should definitely be corrected on the spot.
