John Gill Commentary 2 Samuel 9:5

"Then king David sent, and fetched him out of the house of Machir the son of Ammiel, from Lo-debar." — 2 Samuel 9:5 (ASV)

Then King David sent Messengers; it may be Ziba, none being more proper than he that knew him, and where he was. And fetched him out of the house of Machir, the son of Ammiel, from Lodebar. They demanded him in the king's name, and being delivered to them, they brought him from thence to Jerusalem.
