Adriel in the Bible Encyclopedia - ISBE

a'-dri-el (`adhri'el, "my help is God"): The son of Barzillai the Meholathite, to whom Merab the daughter of King Saul was married when she should have been given to David (1 Sam 18:19; 2 Sam 21:8). "Michal" in 2 Sam 21:8 is a textual error easily accounted for Adriel and Merab had five sons, whom David handed over to the blood vengeance of the men of Gibeon. The name Adriel seems to be Aramaic, the equivalent of the Hebrew name Azriel.
