'Altar of the Lord' in the Bible

Now on that day Joshua made them cutters and gatherers of firewood and water carriers for the congregation and for the altar of the Lord, to this day, in the place which He would choose.

If, however, the land of your possession is unclean, then cross into the land of the possession of the Lord, where the Lord’s tabernacle is situated, and settle down among us. But do not rebel against the Lord, or rebel against us by building an altar for yourselves, besides the altar of the Lord our God [at Shiloh].

So we said, ‘If your descendants should say this to us or to our descendants in time to come, then we can reply, “See the copy of the altar of the Lord which our fathers made, not for burnt offering or for sacrifice, but rather it is a witness between us and you.”’

Far be it from us that we should rebel against the Lord and turn away from following the Lord this day, by building an altar for burnt offering, for grain offering or for sacrifice, besides the altar of the Lord our God which is before His tabernacle [in Shiloh].”
