וַיַּ֗עַל בְּנָיָ֙הוּ֙ בֶּן־יְה֣וֹיָדָ֔ע וַיִּפְגַּע־בּ֖וֹ וַיְמִתֵ֑הוּ וַיִּקָּבֵ֥ר בְּבֵית֖וֹ בַּמִּדְבָּֽר׃
여호야다의 아들 브나야가 곧 올라가서 저를 쳐 죽이매 저가 거친 땅에 있는 자기의 집에 매장되니라
Rashi
In his own house in the wilderness. For his home was unrestricted as a wilderness, to [help] the needy.23See Rashi in Maseches Sanhedrin 49a. Alternatively, Yoav had a house in the wilderness where his shepherds stayed when they were out with the sheep, or Yoav house was free of stolen property just like the wilderness.—Radak.
