1 Samuel 15:5-7

King James Version

⁵ And Saul came to a city of Amalek, and laid wait in the valley.

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.
