'Altar' in the Bible

For the person we are talking about belonged to a different tribe, and no one from that tribe has ever served at the altar.

which had the gold altar for incense and the Ark of the Covenant completely covered with gold. In it were the gold jar holding the manna, Aaron's staff that had budded, and the Tablets of the Covenant.

We have an altar, and those who serve in the tent have no right to eat at it.
