Judges 4:11

Then Moses said to Hobab the son of Reuel the Midianite, Moses’ father-in-law, “We are setting out to the place of which Yahweh said, ‘I will give it to you’; come with us and we will do you good, for Yahweh has promised good concerning Israel.”

Now the sons of the Kenite, Moses’ father-in-law, went up from the city of palms with the sons of Judah, to the wilderness of Judah which is in the south of Arad; and they went and lived with the people.

And Saul said to the Kenites, “Go, depart; go down from among the Amalekites, lest I destroy you with them; you showed lovingkindness to all the sons of Israel when they came up from Egypt.” So the Kenites departed from among the Amalekites.

And Achish said, “Where have you made a raid today?” And David said, “Against the Negev of Judah and against the Negev of the Jerahmeelites and against the Negev of the Kenites.”
