2 Samuel 5:2-4

Amplified Bible

² In times past, when Saul was king over us, it was you who led Israel out [to war] and brought Israel in [from battle]. And the Lord told you, ‘You shall shepherd My people Israel and be ruler over them.’”^{(A) 3} So all the elders (tribal leaders) of Israel came to the king at Hebron, and King David made a covenant with them at Hebron before the Lord; and they anointed him king over Israel. ⁴ David was thirty years old when he became king, and he reigned forty years.
