'Reign' in the Bible

Saul’s son Ish-bosheth was 40 years old when he began his reign over Israel; he ruled for two years. The house of Judah, however, followed David.

David was 30 years old when he began his reign; he reigned 40 years.

During David’s reign there was a famine for three successive years, so David inquired of the Lord. The Lord answered, “It is because of the blood shed by Saul and his family when he killed the Gibeonites.”
