ADRIEL, son of Borzillai, married Merab, daughter of Saul, who had been promised to David, 1 Sam. xviii. 19. Adriel had five sons by her, who were delivered to the Gibeonites to be put to death before the Lord, to avenge the cruelty of Saul, their grandfather, against the GibeoDites. 2 Sam. xxi. 8 imports, that these five were sons of Michal and Adriel ; but either the name of Michal is put for Merab, sister of Michal, or, more probably, Michal had adopted the sons of her sister Merab, who was either dead, or incapable, from some cause, of bringing up her children. Perhaps, too, both sisters may have borne the name of Michal.
