What altar actually means
Altar translates the Hebrew mizbeach, a noun built on zavach, the verb for slaughtering an animal in sacrifice. The form means the place where that happens. An Israelite altar was a raised platform of packed earth or uncut stone where animals were killed, drained, and burned. The same word also covers the small incense altar inside the sanctuary.
Where the word comes from
Hebrew makes place-nouns by putting a mem on the front of a verb. Zavach is to slaughter for sacrifice. Mizbeach is therefore the slaughtering place, in the same way that a Hebrew speaker turns the verb for sitting into the word for a seat. The name is a job description, and the job was butchery.
The building code in Exodus 20 keeps the object crude on purpose. Make it of earth, or of stones you have not touched with an iron tool, and do not put steps up to it. A mound of dirt or a stack of field rocks, low enough to walk up to. Abram built one under the great trees at Mamre when he settled near Hebron. Saul built his first one in the field at Michmash after his troops had eaten meat with the blood still in it, and the text notes it was the first altar he had ever built.
The sanctuary versions were equipment. The courtyard altar had four horns at its corners, and a man in danger of his life could grab them and claim asylum there, which is what both Adonijah and Joab tried during Solomon's succession. Blood was daubed on those horns. The inventory for the temple lists pots, shovels, forks, and basins in polished bronze, because ash and fat and carcass parts had to be moved somewhere. Inside the tent stood a second altar, small, acacia wood plated with gold, where nothing was killed and incense burned twice a day.
Altars also belonged to other gods, and the Hebrew uses the same noun for those. Much of Kings and Chronicles is a running account of whose altars got built and whose got pulled down.
Why "altar" gets in the way
The Hebrew object had a fire kept alight on top of it, a drainage problem, and a smell that carried to the edge of the camp. Current English hangs the word on something else entirely: a table at the front of a church, linen cloth, candles, flowers, a slab of stone or wood where a minister stands with his back to you or facing you depending on the tradition. Readers arrive at Leviticus with that clean picture already installed.
The word also arrives carrying a century of devotional English. Altar call, altar boy, laying something on the altar as a figure of speech for giving God your ambitions. None of that is wrong as English, but it means the reader who meets Jeroboam standing at the altar at Bethel, or Elijah rebuilding the ruined one on Carmel, is imagining church furniture rather than an installation for killing animals in front of a crowd.
Once the picture goes soft, the commands about tearing altars down stop making sense too. Smashing a communion table is vandalism. Smashing a Baal altar is the demolition of a working slaughter site that a whole village depended on, which is why it got people killed.
What this translation prints instead
The NGET prints altar. This is one of the places where the translation keeps a traditional word, because altar is still a live English noun for a place of offering and no plainer replacement covers the ground. Slaughtering place would be accurate for the courtyard altar and flatly wrong for the incense altar, and it would read like a description of an abattoir rather than of worship.
The work gets done by the sentences around the word instead. The translation leaves the physical actions in place rather than smoothing them: blood taken on a finger and sprinkled seven times toward the front of the meeting tent, the leftover grain offering eaten without yeast beside the altar, an altar of acacia wood built for burning incense. A reader who takes those sentences at face value ends up with the right object in mind without the noun having to carry it alone.
Mizbeach is tagged in the text so the note is one tap away. A reader who wants to know why the noun exists finds the slaughtering place there, in the note, while the printed line keeps a word people already recognise instead of trading it for a phrase nobody says out loud.

Questions people ask
What does altar mean in the Bible?
In the Bible an altar is a raised structure where sacrifices are killed and burned. The Hebrew word mizbeach literally means the place of slaughter. Altars ranged from a heap of earth a shepherd built on the spot to the bronze-plated installation in the tabernacle courtyard, complete with horns at the corners and bronze tools for handling ash and fat.
What does altar mean in Hebrew?
The Hebrew is mizbeach, from the verb zavach, to slaughter for sacrifice. The prefixed mem turns a verb into the place where its action happens, so mizbeach means the slaughtering place. The word says nothing about decoration, dedication, or prayer. It names a spot where an animal was killed and burned.
What do the horns of the altar mean?
Four projections at the corners of the altar, made as one piece with it. Blood from certain offerings was put on them, and a person facing execution could grab them and claim sanctuary, which Adonijah and Joab both attempted in 1 Kings. What the horns represented is disputed. Proposals include stylized bull horns, mountain peaks, and a purely practical rig for tying an animal.
What does the altar represent in the Bible?
An offering is transferred from the worshipper to God by fire, and the Hebrew text treats the altar as the equipment that does it. Later Christian writing does read it symbolically, most directly in Hebrews 13, which claims an altar for followers of Jesus that the tabernacle priests had no share in. That is an interpretation added by the New Testament, not the plain sense of Leviticus.
