'Thoughts' in the Bible

(Yea, a sword shall pierce through thy own soul also,) that the thoughts of many hearts may be revealed.

But when Jesus perceived their thoughts, he answering said unto them, What reason ye in your hearts?

But he knew their thoughts, and said to the man which had the withered hand, Rise up, and stand forth in the midst. And he arose and stood forth.

But he, knowing their thoughts, said unto them, Every kingdom divided against itself is brought to desolation; and a house divided against a house falleth.

And he said unto them, Why are ye troubled? and why do thoughts arise in your hearts?
