'Thoughts' in the Bible

Because, knowing God, they glorified him not as God, neither were thankful; but fell into folly in their thoughts, and their heart without understanding was darkened:

who shew the work of the law written in their hearts, their conscience also bearing witness, and their thoughts accusing or else excusing themselves between themselves;)

For I say, through the grace which has been given to me, to every one that is among you, not to have high thoughts above what he should think; but to think so as to be wise, as God has dealt to each a measure of faith.
