Matthew Henry on 2 Samuel 5:11-16
Here is, I. David's house built, a royal palace, fit for the reception of the court he kept and the homage that was paid to him, Sa2 5:11. The Jews were husbandmen and shepherds, and did not much addict themselves either to merchandise or manufactures; and therefore Hiram, king of Tyre, a wealthy prince, when he sent to congratulate David on his accession to the throne, offered him workmen to build him a house. David thankfully accepted the offer, and Hiram's workmen built David a house to his mind. Many have excelled in arts and sciences who were strangers to the covenants of promise.

and there were yet sons and daughters born to David; besides those in Hebron mentioned in 2 Samuel 3:2.
