1 Samuel 13:1, 2
Saul was thirty years old when he became king, and he reigned over Israel forty-two years. / He chose for himself three thousand men of Israel: Two thousand were with Saul at Michmash and in the hill country of Bethel, and a thousand were with Jonathan in Gibeah of Benjamin. And the rest of the troops he sent away, each to his own home.
1 Chronicles 27:1–15
This is the list of the Israelites—the heads of families, the commanders of thousands and of hundreds, and their officers who served the king in every matter concerning the divisions on rotating military duty each month throughout the year. There were 24,000 men in each division: / Jashobeam son of Zabdiel was in charge of the first division, which was assigned the first month. There were 24,000 men in his division. / He was a descendant of Perez and chief of all the army commanders for the first month.
