Albert Barnes Commentary 1 Chronicles 15:1

"And [David] made him houses in the city of David; and he prepared a place for the ark of God, and pitched for it a tent." — 1 Chronicles 15:1 (ASV)

And pitched for it a tent — The old “tent” or “tabernacle” was still in existence at Gibeon (1 Chronicles 16:39; 2 Chronicles 1:3), but the ark had long been separated from it, and David probably thought that something newer and more magnificent was required. He therefore allowed the former tabernacle to keep its place and had another made and erected.
