'Altar of the Lord' in the Bible

Notwithstanding, if the land of your possession be unclean, then come over unto the land of the possession of the LORD, where the LORD's tabernacle dwelleth, and be possessed among us. But rebel not against the LORD nor against us, to build you any other altar save the altar of the LORD our God.

God forbid that we should rebel against the LORD and that we should turn this day from after him, and build an altar for burnt offerings nor sacrifices, save the altar of the LORD our God that is before his tabernacle."
