וַיַּ֗עַל בְּנָיָ֙הוּ֙ בֶּן־יְה֣וֹיָדָ֔ע וַיִּפְגַּע־בּ֖וֹ וַיְמִתֵ֑הוּ וַיִּקָּבֵ֥ר בְּבֵית֖וֹ בַּמִּדְבָּֽר׃
Lalu Benaya anak Yoyada naik, menyerang Yoab, dan membunuhnya. Yoab dikuburkan di rumahnya di padang gurun.
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.
