In 1 Samuel 11, what did Saul do when the Spirit of God came upon him?

He took two oxen and hacked them into pieces, sending the pieces throughout Israel.

The Spirit of God came upon Saul ... and he took a yoke of oxen, and hewed them in pieces, and sent them throughout all the coasts of Israel by the hands of messengers, saying, Whosoever cometh not forth after Saul and after Samuel, so shall it be done unto his oxen. 1 Samuel 11:6-7
