David asked, "Is there anyone remaining from Saul's family I can show kindness to because of Jonathan?"
References for 2 Samuel 9:1
There was a servant of Saul's family named Ziba. They summoned him to David, and the king said to him, "Are you Ziba?" "[I am] your servant," he replied.
So the king asked, "Is there anyone left of Saul's family I can show the kindness of God to?" Ziba said to the king, "There is still Jonathan's son who is lame in both feet."
References for 2 Samuel 9:3
The king asked him, "Where is he?" Ziba answered the king, "You'll find him in Lo-debar at the house of Machir son of Ammiel."
So King David had him brought from the house of Machir son of Ammiel in Lo-debar.
Mephibosheth son of Jonathan son of Saul came to David, bowed down to the ground and paid homage. David said, "Mephibosheth!" "I am your servant," he replied.
"Don't be afraid," David said to him, "since I intend to show you kindness because of your father Jonathan. I will restore to you all your grandfather Saul's fields, and you will always eat meals at my table."
Mephibosheth bowed down and said, "What is your servant that you take an interest in a dead dog like me?"
Then the king summoned Saul's attendant Ziba and said to him, "I have given to your master's grandson all that belonged to Saul and his family.
You, your sons, and your servants are to work the ground for him, and you are to bring in [the crops] so your master's grandson will have food to eat. But Mephibosheth, your master's grandson, is always to eat at my table." Now Ziba had 15 sons and 20 servants.
Ziba said to the king, "Your servant will do all my lord the king commands." So Mephibosheth ate at David's table just like one of the king's sons.
References for 2 Samuel 9:11
Mephibosheth had a young son whose name was Mica. All those living in Ziba's house were Mephibosheth's servants.
However, Mephibosheth lived in Jerusalem because he always ate at the king's table. He was lame in both feet.
