On minor fast days we read Sh'mot 32:11-14 and 34:1-10. The latter is almost the fifth aliyah of Ki Tisa, which is Sh'mot 34:1-9. I've been taught that aliyah boundaries are thoughtful (not arbitrary), and are governed by rules about spacing in the sefer torah and mood. A break between 9 and 10 seems to make sense to me; 10 is the beginning of a multi-verse speech by God. Why is this verse included for the fast-day reading? If v9 is a logical end in Ki Tisa, why isn't it here as well?
