'Peradventure' in the Bible

For I have heard the defaming of many, terror on every side: Report, and we will report it. All my familiars are watching for my stumbling: Peradventure he will be enticed, and we shall prevail against him; and we shall take our revenge on him.

Peradventure they will hearken, and turn every man from his evil way, that I may repent me of the evil which I purpose to do unto them because of the wickedness of their doings.
