כָּל־מַלְכֵ֥י גוֹיִ֖ם כֻּלָּ֑ם שָׁכְב֥וּ בְכָב֖וֹד אִ֥ישׁ בְּבֵיתֽוֹ׃
All the kings of the nations, all of them, sleep in glory, every one in his own house.
Rashi on Isaiah
each in his house In his grave, and so did Jonathan render: In his eternal house.
Ibn Ezra on Isaiah
In his house. Which he had prepared for himself, that is the grave; comp. man goeth to his long home (Eccl. 12:5)
