1 Samuel 11:10-12 New International Version - UK (NIVUK)
10 They said to the Ammonites, ‘Tomorrow we will surrender to you, and you can do to us whatever you like.’
11 The next day Saul separated his men into three divisions; during the last watch of the night they broke into the camp of the Ammonites and slaughtered them until the heat of the day. Those who survived were scattered, so that no two of them were left together.
Saul confirmed as king
12 The people then said to Samuel, ‘Who was it that asked, “Shall Saul reign over us?” Turn these men over to us so that we may put them to death.’
