The verse in Esther 6:11 describing Haman's pulling Mordochai on the streets says:
כָּכָה יֵעָשֶׂה לָאִישׁ אֲשֶׁר הַמֶּלֶךְ חָפֵץ בִּיקָרוֹ
So shall it be done unto the man whom the king delighteth to honour.
The verse in Devarim 25:9 states regarding someone who perfoms Chalitza with his brother's widow:
כָּכָה יֵעָשֶׂה לָאִישׁ אֲשֶׁר לֹא-יִבְנֶה אֶת-בֵּית אָחִיו
So shall it be done unto the man that doth not build up his brother's house.
Both phrases start with the same four-word phrase which is found nowhere else in Tanach. Additionally, they have the same cantallation notes associated with them.
These seem very parallel. Does anyone know of a good connection between the two situations, or any classical (loosely defined) commentators who address the issue?
