Ibn Ezra
If Scripture had only said in the camp , it would be permissible to slaughter animals anywhere outside of the camp. The commandment that is herein given also applies to the Temple; but there it covers only the districts close to Jerusalem (the definition of “close” is known from tradition [Qiddushin 57b]). In faraway places one may simply slaughter the animal and eat its flesh (for so it is written [Deuteronomy 12:21]). Many people have incorrectly said that, during the Exile, all flesh is forbidden. They assert that the passage “nor did meat or wine come into my mouth” [Daniel 10:3] denotes an additional abstinence from the flesh of fish. I do not wish to spend time refuting them.
Ibn Ezra
annoint from “nor did I annoint myself at all” [Daniel 10: 3]. Scripture describes the situation that is the opposite of “oil upon your head” [Ecclesiastes 9: 8].
