'Thoughts' in the Bible

O Jerusalem, wash thy heart from wickedness, that thou mayest be saved. How long shall thine evil thoughts lodge within thee?

Hear, O earth: behold, I will bring evil upon this people, even the fruit of their thoughts, because they have not hearkened unto my words; and as for my law, they have rejected it.

For I know the thoughts that I think toward you, saith Jehovah, thoughts of peace, and not of evil, to give you hope in your latter end.
