What does the word shlemiel have to do with the fifth day of Chanukkah?
Today's reading, the fifth day of Chanukkah, is about the offering of Shlumiel.
"One suggestion relates to the arcane permutations of the Hebrew calendar. On Hanukkah a different section of Numbers 7 is recited daily, recounting the gifts of the tribal chieftains who each brought a daily offering at the dedication of the Tabernacle (mishkan). On the first day of Hanukkah, the first chieftain’s name appears at the beginning, on the second day the second chieftain’s name, and so on. (On the eighth day, the gifts of chieftains 8-12 are read.)
The exception is the Sabbath during Hanukkah, when the Torah portion is that of the regular weekly cycle and the added maftir reading from a second scroll is the Hanukkah reading beginning with the daily chieftain. Only one day of Hanukkah’s eight never falls on a Sabbath: the fifth day. And which chieftain therefore never stars on the Sabbath, when the synagogue is far better attended than on a midwinter weekday morning? Why, Shelumiel ben Tsurishaddai, of course. Who else?" - (From Balashon)
