Rashi on Deuteronomy 12:11/רש"י על דברים י״ב:י״א

1והיה המקום וגו׳ IT SHALL BE [THAT YE SHALL BRING TO] THE PLACE [WHICH THE LORD YOUR GOD SHALL CHOOSE … EVEN THITHER YE SHALL BRING ALL THAT I COMMAND YOU] — then build the “Chosen House” for yourselves in Jerusalem. And so indeed it states of David, (II Samuel 7:1, 2): “And it came to pass when the king sat in his house, and the Lord had given him rest round about from all his enemies, that the king said unto Nathan the prophet, ‘See now, I dwell in the house of cedar, but the Ark of God dwelleth within curtains …'” (Sifrei Devarim 67:3; cf. Rashi on that verse).

2שמה תביאו THITHER SHALL YE BRING [ALL THAT I COMMAND YOU] — Above (v. 6) it (the same expression) is said in reference to Shiloh, but here it is said in reference to Jerusalem. It is for the following reason that Scripture divides the matter into two paragraphs: to give permission to offer on a Bamah in the intermediate period between the existence of the one sanctuary and the other; viz., that after Shiloh was destroyed and they came to Nob and erected the Tabernacle there, and then again when Nob was destroyed and they came to Gibeon, sacrificing on the Bamah was allowed until they finally came to Jerusalem (Zevachim 119a and Mishnah Zevachim 14:1).

3מבחר נדריכם YOUR CHOICE VOWS — This teaches that one should bring one’s offerings from the choicest (Sifrei Devarim 68:4).
