5 Then he and his men went to the city of Amalek and waited in ambush in a dry riverbed.
6 He sent a warning to the Kenites, a people whose ancestors had been kind to the Israelites when they came from Egypt: “Go away and leave the Amalekites, so that I won't kill you along with them.” So the Kenites left.
7 Saul defeated the Amalekites, fighting all the way from Havilah to Shur, east of Egypt;
8 he captured King Agag of Amalek alive and killed all the people.
9 But Saul and his men spared Agag's life and did not kill the best sheep and cattle, the best calves and lambs, or anything else that was good; they destroyed only what was useless or worthless.
10 The Lord said to Samuel,
11 “I am sorry that I made Saul king; he has turned away from me and disobeyed my commands.” Samuel was angry, and all night long he pleaded with the Lord.
