Hastings
1. A son of Seir (Ge 36:21 = 1Ch 1:38). 2. A son of Anah and grandson of Seir (Ge 36:25, cf. Ge 36:30 = 1Ch 1:41; Dishon should also be read for Massoretic Text Dishan in Ge 36:26). Dishan and Dishon are, of course, not individual names, but the eponyms of Horite clans. Their exact location is a matter of uncertainty.
