2 Chronicles 7:13-14

If I shut up heaven that there be no rain, or if I command the locusts to devour the land, or if I send pestilence among my people; if my people, which are called by my name, shall humble themselves, and pray, and seek my face, and turn from their wicked ways; then will I hear from heaven, and will forgive their sin, and will heal their land.
