2 Samuel 5:1-5

1Then all the tribes of Israel came to David at Hebron and spoke saying, “Here we are, your own flesh and blood.

2Even before, when Saul was king over us, it was you who led Israel out and back. Also Adonai said to you, ‘You will shepherd My people Israel and be ruler over Israel.’”

3So all the elders of Israel came to the king at Hebron, and King David cut a covenant with them at Hebron before Adonai. Then they anointed David king over Israel.

4David was 30 years old when he began to reign and he reigned 40 years.

5In Hebron he reigned over Judah seven years and six months, and in Jerusalem he reigned 33 years over all Israel and Judah.
