A son of Barzillai, married Merab, daughter of Saul, who had been promised to David, 1 Samuel 18:19 . Adriel had five sons by her, who were delivered up to the Gibeonites, to be put to death before the Lord, to avenge the cruelty of Saul their grandfather against the Gibeonites. In 2 Samuel 21:8 , these are said to be the sons of Michal, whom she "brought up" for Adriel; but unless this is a copyist's error, Michal had adopted the children of her sister Merab, who was perhaps dead; or possibly both sisters may have borne the name Michal.
