2 Samuel 24:3, 18

And Joab said unto the king, Now Jehovah thy God add unto the people, how many soever they may be, a hundredfold; and may the eyes of my lord the king see it: but why doth my lord the king delight in this thing?

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