'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 the LORD is contemptible.

Who is there even among you that would shut the doors for nought? neither do ye kindle fire on mine altar for nought. I have no pleasure in you, saith the LORD of hosts, neither will I accept an offering at your hand.

And this have ye done again, covering the altar of the LORD with tears, with weeping, and with crying out, insomuch that he regardeth not the offering any more, or receiveth it with good will at your hand.
