A son of Joktan (Gen. x. 27, and the corresponding genealogical list, I Chron. i. 21). The names of the other sons of Joktan point clearly to an Arabic origin, and it is quite reasonable to suppose that Diklah also had in Arabic home. in Arabic is a common word meaning "date-palm." An Assyrian origin is suggested by Hommel because of the similarity between "Diklah" and the name of the Tigris—"Diḳlath" in Aramaic, and "Idiḳlat" in Assyrian.
