Abiel in Fausset's Bible Dictionary

("father of strength".) 1. Father of Kish and of Ner; grandfather of Saul and of Abner, according to 1 Samuel 9:1; 1 Samuel 14:51. But Abiel seems to have had "Ner" as his second name (1 Chronicles 8:33; 1 Chronicles 9:35; 1 Chronicles 9:39, where Abiel is also called Jehiel and Saul is represented as his great grandson). Probably in 1 Samuel a link in the genealogy is omitted, as often elsewhere. 2. 1 Chronicles 11:32; named Abi-Albon (of the same meaning) 2 Samuel 23:31.
