1 Samuel 11:7-8

So he took a pair of oxen and cut them into pieces. Then he gave the pieces of the oxen to messengers and ordered them to carry them through all the land of Israel. The messengers said, “This is what will happen to the oxen of anyone who does not follow Saul and Samuel.” So the people became very afraid of the LORD. They all came together as if they were one person. Saul gathered the people together at Bezek. There were three hundred thousand men from Israel and thirty thousand men from Judah.
