'Descendants' in the Bible

The sons of [Jethro] the Kenite, Moses’ father-in-law, went up from the City of Palms (Jericho) with the sons of Judah, to the wilderness of Judah which is in the Negev (South country) near Arad; and they went and lived with the people.

Now Heber the Kenite had separated himself from the Kenites, from the sons of Hobab the father-in-law of Moses, and had pitched his tent as far away as the terebinth tree in Zaanannim, which is near Kedesh.

And Gideon said to them, “I would make a request of you, that each one of you give me an earring from his spoil.” For the Midianites had gold earrings, because they were Ishmaelites [who customarily wore them].
