'Sudden' in the Bible

Elijah took off his ornamented cloak, wrapped it up in a roll, struck the water, and all of a sudden the water divided into two parts! One side of the river stood still opposite the other until the two of them crossed over on dry ground.

Elisha took hold of Elijah's ornamental cloak that had been left behind, struck the water, and cried out: "Where is the LORD God of Elijah?" All of a sudden, after he had struck the water, the water divided into two parts! One side of the river stood opposite the other, and Elisha crossed over.

When the king heard what the woman said, he ripped his garments as he continued walking along the city wall. As the people watched, all of a sudden they noticed he was wearing sackcloth underneath his clothes, inside next to his flesh!
