2 Samuel 9:10

9:10 You will cultivate the land for him – you and your sons and your servants. You will bring its produce and it will be food for your master’s grandson to eat. But Mephibosheth, your master’s grandson, will be a regular guest at my table.” (Now Ziba had fifteen sons and twenty servants.)

2 Samuel 21:8

21:8 So the king took Armoni and Mephibosheth, the two sons of Aiah’s daughter Rizpah whom she had born to Saul, and the five sons of Saul’s daughter Merab whom she had born to Adriel the son of Barzillai the Meholathite.
