Commentary on 2 Samuel 9:3

• Matthew Henry (Presbyterian), Matthew Henry's Complete Commentary on 2 Samuel 9:1-8: Here is, I. David's enquiry after the remains of the ruined house of Saul, Sa2 9:1. This was a great while after his accession to the throne, for it should seem that Mephibosheth, who was but five years old when Saul died, had now a son born, Sa2 9:12. David had too long forgotten his obligations to Jonathan, but now, at length, they are brought to his mind.
