'Altar' in the Bible
Then Joshua built an altar for the Lord God of Israel on Mount Ebal,
and that day made them woodcutters and water carriers for the community and for the altar of the Lord at the divinely chosen site. (They continue in that capacity to this very day.)
The Reubenites, Gadites, and half-tribe of Manasseh came to Geliloth near the Jordan in the land of Canaan and built there, near the Jordan, an impressive altar.
The Israelites received this report: "Look, the Reubenites, Gadites, and half-tribe of Manasseh have built an altar at the entrance to the land of Canaan, at Geliloth near the Jordan on the Israelite side."
"The entire community of the Lord says, 'Why have you disobeyed the God of Israel by turning back today from following the Lord? You built an altar for yourselves and have rebelled today against the Lord.
But if your own land is impure, cross over to the Lord's own land, where the Lord himself lives, and settle down among us. But don't rebel against the Lord or us by building for yourselves an altar aside from the altar of the Lord our God.
If we have built an altar for ourselves to turn back from following the Lord by making burnt sacrifices and grain offerings on it, or by offering tokens of peace on it, the Lord himself will punish us.
So we decided to build this altar, not for burnt offerings and sacrifices,
We said, 'If in the future they say such a thing to us or to our descendants, we will reply, "See the model of the Lord's altar that our ancestors made, not for burnt offerings or sacrifices, but as a reminder to us and you."'
Far be it from us to rebel against the Lord by turning back today from following after the Lord by building an altar for burnt offerings, sacrifices, and tokens of peace aside from the altar of the Lord our God located in front of his dwelling place!"
The Reubenites and Gadites named the altar, "Surely it is a Reminder to us that the Lord is God."
