1 Samuel 13:2-4

2Now Saul chose for himself 3,000 men of Israel, of which 2,000 were with Saul in Michmas and in the hill country of Beth-el, and 1,000 were with Jonathan in Gibeah of Benjamin. The rest of the troops he sent away, each one to his tent.

3Now Jonathan struck down the garrison of the Philistines that was in Geba, and the Philistines heard of it. So Saul blew the shofar throughout the country, saying, “Let the Hebrews hear.”

4All Israel heard the news, “Saul had struck down the garrison of the Philistines, so Israel has become a stench to the Philistines.” Then the people were summoned to Saul at Gilgal.
