1 Samuel 11:7-8

He took a team of oxen and cut them in pieces, and sent them throughout the territory of Israel by the hand of messengers, saying, “Whoever does not come out to follow Saul and Samuel, the same shall be done to his oxen.” Then fear of the LORD fell on the people, and they came out [united] as one man [with one purpose]. He assembled and counted them at Bezek; and the sons of Israel numbered 300,000, and the men of Judah 30,000.
