A Kaye asked:
In discussing the two great lights you refer to Yoma 62b where the gemara comments that plural implies at least two so the fact the Torah states two goats means we have to learn something special about them, namely that they must be identical. Why does it not just mean they are just two goats and lights, not three or more? Why look for more complex reasons?
The Kollel replies:
When the Torah writes a plural and does not specify how many, it must mean two, for if
it meant more then the Torah would specify. When the Torah specifies "two goats," it is unnecessary to specify the number two, because "goats" means two goats already. It must be that the Torah is teaching us something else about the duality of the goats -- i.e. they must be identical.
