כִּ֚י כָּל־שֻׁלְחָנ֔וֹת מָלְא֖וּ קִ֣יא צֹאָ֑ה בְּלִ֖י מָקֽוֹם׃ (ס)
For all tables are full of filthy vomit, and no place is clean.
Rashi on Isaiah
For all tables I.e., all their tables are of sacrifices for the dead, i.e., the pagan deities, which are like vomit and ordure.
Ibn Ezra on Isaiah
For all tables are full of vomit, etc. This is usually the case with drunken people.
