'Altar to the Lord' in the Bible

And Gad came that day to David, and said to him, Go up, rear an altar to the LORD in the threshing-floor of Araunah the Jebusite.

And Araunah said, Why is my lord the king come to his servant? And David said, To buy the threshing-floor of thee, to build an altar to the LORD, that the plague may be stayed from the people.

And David built there an altar to the LORD, and offered burnt-offerings and peace-offerings. So the LORD was entreated for the land, and the plague was stayed from Israel.
