Read 1 Samuel 11:11 Using Other Translations
And it was so on the morrow, that Saul put the people in three companies; and they came into the midst of the host in the morning watch, and slew the Ammonites until the heat of the day: and it came to pass, that they which remained were scattered, so that two of them were not left together.
And the next day Saul put the people in three companies. And they came into the midst of the camp in the morning watch and struck down the Ammonites until the heat of the day. And those who survived were scattered, so that no two of them were left together.
But before dawn the next morning, Saul arrived, having divided his army into three detachments. He launched a surprise attack against the Ammonites and slaughtered them the whole morning. The remnant of their army was so badly scattered that no two of them were left together.
