1 Samuel 15:6

And Saul said unto the Kenites, a small tribe of nomads friendly to Israel, with whom they had come up from the wilderness under the leadership of Hobab, Judges 1:16, Go, depart, get you down from among the Amalekites, lest I destroy you with them; for ye showed kindness to all the children of Israel when they came up out of Egypt, Numbers 10:29. So the Kenites departed from among the Amalekites.
