2 Samuel 21:7-8

21:7 The king had mercy on Mephibosheth son of Jonathan, the son of Saul, in light of the Lord’s oath that had been taken between David and Jonathan son of Saul. 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.
