I think 2 Chron 7:13 should always be included when verse 14 is quoted, it completes what God is saying here.
When I shut up the heavens so that there is no rain, or command the locust to devour the land, or send pestilence among my people, 14 if my people who are called by my name humble themselves, and pray........
No matter what you add to it, there’s no mistaking the requirement in verse 14 to turn from wickedness.
