1 Samuel 11:9-12

9They said to the messengers who had come, “You shall say to the men of Jabesh-gilead: ‘Tomorrow, by the time the sun is hot, you will have help [against the Ammonites].’ ” So the messengers came and reported this to the men of Jabesh; and they were overjoyed.

10So the men of Jabesh said [to Nahash the Ammonite], “Tomorrow we will come out to you [to surrender], and you may do to us whatever seems good to you.”

11The next morning Saul put the men into three companies; and they entered the [Ammonites’] camp during the [darkness of the early] morning watch and killed the Ammonites until the heat of the day; and the survivors were scattered, and no two of them were left together.

12The people said to Samuel, “Who is the one who said, ‘Shall Saul reign over us?’ Bring the men, and we will put them to death.”
