2 Samuel 9:3ESV·author unknown

And the king said, “Is there not still someone of the house of Saul, that I may show the kindness of God to him?” Ziba said to the king, “There is still a son of Jonathan; he is crippled in his feet.”

Matthew Henry Presbyterian @wholebiblehenry

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.

John Gill Reformed Baptist @doctorgill

And the king said, is there not yet any of the house of Saul; that is, remaining or living: that I may show the kindness of God unto him? great kindness, some large favour or benefit; for the word God added to things, as to trees, mountains, &c.

Geneva Bible Notes Reformed @genevanotes

And the king said, [Is] there not yet any of the house of Saul, that I may shew the kindness of God unto him? And Ziba said unto the king, Jonathan hath yet a son, [which is] lame on [his] feet. (b) Such mercy as shall be acceptable to God.
