'Altar of the Lord' in the Bible

And that day Joshua made them servants, cutting wood and getting water for the people and for the altar of the Lord, in the place marked out by him, to this day.

But if the land you now have is unclean, come over into the Lord's land where his House is, and take up your heritage among us: but do not be false to the Lord and to us by building yourselves an altar in addition to the altar of the Lord our God.

Never let it be said that we were false to the Lord, turning back this day from him and building an altar for burned offerings and meal offerings and offerings of beasts, in addition to the altar of the Lord our God which is before his House.
