I Samuel 11:8-11

When he numbered them in Bezek, the children of Israel were three hundred thousand, and the men of Judah thirty thousand. And they said to the messengers who came, “Thus you shall say to the men of Jabesh Gilead: ‘Tomorrow, by the time the sun is hot, you shall have help.’ ” Then the messengers came and reported it to the men of Jabesh, and they were glad. Therefore the men of Jabesh said, “Tomorrow we will come out to you, and you may do with us whatever seems good to you.” So it was, on the next day, that Saul put the people in three companies; and they came into the midst of the camp in the morning watch, and killed Ammonites until the heat of the day. And it happened that those who survived were scattered, so that no two of them were left together.
