What does 1 Samuel 11:7 mean?

He took a pair of oxen, cut them into pieces, and sent the pieces throughout Israel with messengers, saying, 'This is what will happen to the oxen of anyone who doesn't follow Saul and Samuel.' The Lord made everyone afraid, so they all came out together as one army. 1 Samuel 11:7 - Modern Text Bible

(Saul uses a shocking message to rally the people, and God makes sure everyone takes it seriously.)
