'Sovereignty' in the Bible

Then all the assembly made a covenant in the house of God with the king [that is, with the child Joash, to overthrow Athaliah by proclaiming his sovereignty]. And Jehoiada [the priest] said to them, “Behold, the king’s son [Joash] shall reign, as the Lord has said in regard to the sons of David.
