וַיֹּצִ֨יאוּ אֹת֜וֹ כָּל־הָעֵדָ֗ה אֶל־מִחוּץ֙ לַֽמַּחֲנֶ֔ה וַיִּרְגְּמ֥וּ אֹת֛וֹ בָּאֲבָנִ֖ים וַיָּמֹ֑ת כַּאֲשֶׁ֛ר צִוָּ֥ה יְהוָ֖ה אֶת־מֹשֶֽׁה׃ (פ)
Levaram-no, pois, para fora do arraial, e o apedrejaram, de modo que ele morreu; como o SENHOR ordenara a Moisés.
Rashi on Numbers
ויציאו אתו AND [ALL THE CONGREGATION] BROUGHT HIM OUTSIDE [THE CAMP] — From here we learn that the place of stoning was outside and distant from the seat of the Beth Din (Sifrei Bamidbar 114).
