After David was crowned king in Hebron, he conquered Jerusalem and defeated the Philistines. Our haftarah picks up just following these events, when King David decides to bring the Ark of the Covenant up to Jerusalem from the home of Abinadav, where it had remained since being returned to the Land of Israel by the Philistines in the time of Samuel. Thus, our haftarah begins with the Ark at rest in the home of Abinadav and ends with the promise of its future home in the Temple.
