Genesis 15:19

Cineans, in Arabia, of which nation was Jethro. They were permitted to dwell in the tribe of Juda, and served the Hebrews. --- Cenezites, who probably inhabited the mountains of Juda. --- Cedmonites, or eastern people, as their name shews. Cadmus was of this nation, of the race of the Heveans, dwelling in the environs of mount Hermon, whence his wife was called Hermione. He was, perhaps, one of those who fled at the approach of Josue; and was said to have sowed dragons' teeth, to people his city of Thebes in Beotia, from an allusion to the name of the Hevites, which signifies serpents. (Calmet) --- The eleven nations here mentioned were not all subdued; on account of the sins of the Hebrews. (Menochius)
