'Altar of the Lord' in the Bible

And Joshua made them that day hewers of wood and drawers of water for the congregation, and for the altar of the LORD, even unto this day, in the place which he should choose.

Nevertheless, if the land of your possession is unclean, then pass over unto the land of the possession of the LORD, in which the LORD'S tabernacle dwells, and take possession among us: but rebel not against the LORD, nor rebel against us, in building you an altar besides the altar of the LORD our God.

Therefore said we, that it shall be, when they should so say to us or to our generations in time to come, that we may say again, Behold the pattern of the altar of the LORD, which our fathers made, not for burnt offerings, nor for sacrifices; but it is a witness between us and you.

God forbid that we should rebel against the LORD, and turn this day from following the LORD, to build an altar for burnt offerings, for grain offerings, or for sacrifices, besides the altar of the LORD our God that is before his tabernacle.
