What is the significance of the fact that the bulls on Sukos diminish each day?
Rashi #1 (in Pasuk 18) and Targum Yonasan: They add up to seventy, 1 corresponding to the seventy nations, and serve as a hint that they will diminish slowly but surely. 2
Rashi (in Pasuk 36), citing Midrash Tanchuma): This teaches us Derech Eretz ? That on the first day one serves one's guest juicy fowl, on the second day, fish, then meat, then legumes and finally vegetables. 3
What is the significance of the fourteen lambs that were brought on each day of Sukos?
How did the twenty-four groups of Kohanim that served in the Beis-Hamikdash on Yom-Tov distribute the Avodas ha'Korbanos on Sukos?
Targum Yonasan and Sukah 55b: Thirteen groups brought one bull each, two brought one ram each, one brought the goat, eight brought one lamb each, and six of those who brought bulls also brought a lamb. 1
All of which was decided by a lottery. And on each successive day, one less group brought a bull, until, on the seventh day, each group brought one animal. See Targum Yonasan on each day.
