1 Samuel 15:6-8

King James Version

⁶ And Saul said unto the Kenites, Go, depart, get you down from among the Amalekites, lest I destroy you with them: for ye shewed kindness to all the children of Israel, when they came up out of Egypt. So the Kenites departed from among the Amalekites.

⁷ And Saul smote the Amalekites from Havilah until thou comest to Shur, that is over against Egypt.

⁸ And he took Agag the king of the Amalekites alive, and utterly destroyed all the people with the edge of the sword.
