1 Chronicles 22:1 - Clarke's commentary and critical notes on the Bible

Then David said, This is the house of the LORD God, and this is the altar of the burnt offering for Israel. David said, This is the house of the Lord - Till a temple is built for his name, this place shall be considered the temple of God; and on this altar, and not on that at Gibeon, shall the burnt-offerings of Israel be made. David probably thought that this was the place on which God designed that his house should be built; and perhaps it was this that induced him to buy, not only the threshing-floor, but probably some adjacent ground also, as Calmet supposes, that there might be sufficient room for such a building.
