'Altar to the Lord' in the Bible
Then the angel of the Lord commanded Gad to say to David that David should go up and set up an altar to the Lord in the threshing floor of Ornan the Jebusite.
Then David said to Ornan, "Give me this threshing-floor plot so that I may build an altar to the Lord on it. Give it to me for the full price, so the plague on the people may be halted."
And David built there an altar to the Lord and offered burnt offerings and peace offerings and called upon the Lord; and He answered him by fire from heaven upon the altar of burnt offering.
