2 Samuel 5:3-5

3So King David made an agreement with the leaders of Israel when they came to him at Hebron. They made promises in the Lord's name. Then they anointed David to be king over Israel.

4David was 30 years old when he became king. He ruled Israel as king for 40 years.

5He ruled over Judah in Hebron for seven years and six months. And in Jerusalem he ruled over all Israel and Judah for 33 years.
