'Descendants' in the Bible

And the descendants of the Ken'ite, Moses' father-in-law, went up with the people of Judah from the city of palms into the wilderness of Judah, which lies in the Negeb near Arad; and they went and settled with the people.

Now Heber the Ken'ite had separated from the Ken'ites, the descendants of Hobab the father-in-law of Moses, and had pitched his tent as far away as the oak in Za-anan'nim, which is near Kedesh.
