신명기 12:13 해설: Rashi, Chizkuni, Ibn Ezra & Rabbeinu Bahya

השמר לך TAKE HEED TO THYSELF [LEST THOU OFFER THY BURNT OFFERINGS IN EVERY PLACE THAT THOU SEEST] — This negative form of the positive command in v. 11, is stated in order to attach a negative command (לאו) to this matter (Sifrei Devarim 70:1).

השמר לך פן תעלה עולותיך בכל מקום, “Take heed not to offer your burnt offerings at any place;” the reason why the Torah is so insistent that offerings not be brought other than at a central location, is that seeing the Israelites are supposed to make at least three pilgrimages a year to the Temple in Jerusalem, if they were legally able to offer the sacrifices that they need to offer also on private altars, many would use that as an excuse not to make the pilgrimages to Jerusalem. Once they would get into the habit to offer sacrifices to Hashem on private altars, it would be a small step to also offer some sacrifices, such as calves, to other “deities.” [As we saw once Jerobam erected these calves by blocking the highways to Jerusalem to pilgrims. (Compare Kings I chapter 12) Ed.]

Scripture repeats the idea of in every place which you deem suitable [cf.: 8] in order to exclude meat of luxury. Since peace-offerings are holy, and since a ritually impure person who eats holy meat incurs excision, Scripture clarifies that meat of luxury may be eaten by the ritually impure and the ritually pure.

בכל מקום אשר תראה IN EVERY PLACE THAT “THOU” SEEST — i.e., that enters thy mind, but thou mayest offer anywhere by the command of a prophet, as, for instance, Elijah did on Mount Carmel (1 Kings 18:21 ff.) (Sifrei Devarim 70:3).
