Jerusalem - See Judges 1:8 note.
His tent - Perhaps the tabernacle. David had neither tent nor house of his own. It would be quite in accordance with David’s piety that he should immediately dedicate to God the arms taken from the Philistine, in acknowledgment that the victory was not his own but the Lord’s (compare 1 Samuel 21:9). His tabernacle, meaning the tabernacle which he had pitched (2 Samuel 6:17; compare Acts 15:16).
