2 Samuel 5:1-4

1All the tribes of Israel came to David at Hebron. “We are your own flesh and blood,” they said.

2“Even in the past when Saul ruled us, you were the one who led Israel in battle. The Lord has said to you, ‘You will be shepherd of my people Israel, the leader of Israel.’ ”

3All the leaders of Israel had come to Hebron. King David made an agreement with them at Hebron in front of the Lord. So they anointed David king of Israel.

4David was 30 years old when he became king, and he ruled for 40 years.
