'Suddenly' in the Bible

When they began to shout and praise, the Lord suddenly attacked the Ammonites, Moabites, and men from Mount Seir who were invading Judah, and they were defeated.

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.

And Hezekiah rejoiced, and all the people, that God had prepared the people: for the thing was done suddenly.
