ADRIEL (Heb. אַדְרִיאֵל; "God is my help"), son of Barzillai the Meholathite; the husband of *Merab, the daughter of Saul (i Sam. 18:19). Saul pledged his daughter Merab to David; however, when the time came to fulfill his promise, he gave her to Adriel. Critics have suggested that the name Michal in ii Samuel 21:8 is an error for Merab (which is read by the Lucianic recension of the Septuagint and by the Peshitta). David handed over the five sons of Adriel and Merab to the Gibeonites for impalement (ii Sam. 21:8–10).
