1 Samuel 11:1-2, 5-7

Then Nahash the Ammonite came up, and encamped against Jabesh-gilead: and all the men of Jabesh said unto Nahash, Make a covenant with us, and we will serve thee. And Nahash the Ammonite answered them, On this condition will I make a covenant with you, that I may thrust out all your right eyes, and lay it for a reproach upon all Israel.

And, behold, Saul came after the herd out of the field; and Saul said, What aileth the people that they weep? And they told him the tidings of the men of Jabesh. And the Spirit of God came upon Saul when he heard those tidings, and his anger was kindled greatly. 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. And the fear of the LORD fell on the people, and they came out with one consent.
