'Altar' in the Bible

For the one concerning whom these things are spoken belongs to another tribe, from which no one has officiated at the altar.

having a golden altar of incense and the ark of the covenant covered on all sides with gold, in which was a golden jar holding the manna, and Aaron’s rod which budded, and the tables of the covenant;

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