1 Samuel 11:7

and taking two heifers, he cut them in pieces, and sent them to all the borders of Israel, by the hands of messengers, saying, So shall be done to every man’s cattle who goeth not out after Saul and after Samuel. And a dread of the Lord came on all the people of Israel, and they came out as one man.

And he took two cows, and cut them in pieces, and sent them into all the coasts of Israel by the hand of messengers, saying, Whoso comes not forth after Saul and after Samuel, so shall they do to his oxen: and a transport from the Lord came upon the people of Israel, and they came out to battle as one man.
