II Samuel 5:3

3 When all the elders of Israel had come to King David at Hebron, the king made a covenant with them at Hebron before the Lord, and they anointed David king over Israel.

3 So all the responsible men of Israel came to the king at Hebron; and King David made an agreement with them in Hebron before the Lord: and they put the holy oil on David and made him king over Israel.
