'Table of the Lord' in the Bible

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.

But ye have profaned it, in that ye say, The table of the LORD is polluted; and the fruit thereof, even his meat, is contemptible.

Ye cannot drink the cup of the Lord, and the cup of demons: ye cannot partake of the table of the Lord, and of the table of demons.
