'Altar' in the Bible

Yet the one these things are spoken about belongs to a different tribe, and no one from that tribe has ever officiated at the altar.

It contained the golden altar of incense and the ark of the covenant covered entirely with gold. In this ark were the golden urn containing the manna, Aaron's rod that budded, and the stone tablets of the covenant.

We have an altar that those who serve in the tabernacle have no right to eat from.
