Esther 1:6, Question 1. Why does this verse start with a large letter “ches?”

ו חוּר כַּרְפַּס וּתְכֵלֶת אָחוּז בְּחַבְלֵיבוּץ וְאַרְגָּמָן עַלגְּלִילֵי כֶסֶף וְעַמּוּדֵי שֵׁשׁ מִטּוֹת זָהָב וָכֶסֶף עַל רִצְפַת בַּהַטוָשֵׁשׁ וְדַר וְסֹחָרֶת

According to Rav Shlomo Alkabetz, the famed kabbalist and author of the song Licha Dodi, one of the reasons for the large letter “ches” is due to its gematria (8) being the same as the number of clothes worn by the Kohen Gadol, and is thus yet another indication (as before) that Achashverosh was wearing priestly clothing.
