2 Chronicles 7:13-14

13If I shut up the heavens so that no rain falls, or if I command locusts to devour the land, or if I send pestilence and plague among My people,

14and My people, who are called by My Name, humble themselves, and pray and seek (crave, require as a necessity) My face and turn from their wicked ways, then I will hear [them] from heaven, and forgive their sin and heal their land.
