2 Samuel 5:1-5 NRS

1 Then all the tribes of Israel came to David at Hebron, and said, "Look, we are your bone and flesh.
2 For some time, while Saul was king over us, it was you who led out Israel and brought it in. The Lord said to you: It is you who shall be shepherd of my people Israel, you who shall be ruler over Israel."
3 So all the elders of Israel came to the king at Hebron; and King David made a covenant with them at Hebron before the Lord, and they anointed David king over Israel.
4 David was thirty years old when he began to reign, and he reigned forty years.
5 At Hebron he reigned over Judah seven years and six months; and at Jerusalem he reigned over all Israel and Judah thirty-three years.
