1 Samuel 11:6-7
6-7The Spirit of God came on Saul when he heard the report and he flew into a rage. He grabbed the yoke of oxen and butchered them on the spot. He sent the messengers throughout Israel distributing the bloody pieces with this message: "Anyone who refuses to join up with Saul and Samuel, let this be the fate of his oxen!"
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.
