'Altar' 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 Jehovah is contemptible.

Oh that there were one among you that would shut the doors, that ye might not kindle fire on mine altar in vain! I have no pleasure in you, saith Jehovah of hosts, neither will I accept an offering at your hand.

And this again ye do: ye cover the altar of Jehovah with tears, with weeping, and with sighing, insomuch that he regardeth not the offering any more, neither receiveth it with good will at your hand.
