1 Samuel 11:7-8
7-8The terror of God seized the people, and they came out, one and all, not a laggard among them. Saul took command of the people at Bezek. There were 300,000 men from Israel, another 30,000 from Judah.
9-11Saul instructed the messengers, "Tell this to the folk in Jabesh Gilead: 'Help is on the way. Expect it by noon tomorrow.'"
The messengers set straight off and delivered their message. Elated, the people of Jabesh Gilead sent word to Nahash: "Tomorrow we'll give ourselves up. You can deal with us on your terms." Long before dawn the next day, Saul had strategically placed his army in three groups. At first light they broke into the enemy camp and slaughtered Ammonites until noon. Those who were left ran for their lives, scattering every which way.
