By presenting defiled food on My altar. But you ask, ‘How have we defiled You ?’ By saying that the table of the LORD is contemptible.
Jewish Publication Society of America Version (JPS1917) - Malachi 1:7 >Ye offer polluted bread upon Mine altar. And ye say: 'Wherein have we polluted thee?' In that ye say: 'The table of the LORD is contemptible.'
