'Altar' in the Bible

By presenting defiled food on my altar. And you ask, "How have we defiled you?' By saying, "The Table of the LORD is contemptible.'

"Oh, that one of you would shut the Temple doors and not light useless fires on the altar! I'm not pleased with you," says the LORD of the Heavenly Armies, "and I'll accept no offerings from you.

"This is another thing you do: you flood the altar of the LORD with tears, weeping and wailing because he no longer pays attention to your offering nor takes pleasure in it from your hand.
