'Thoughts' in the Bible

For the wise person thinks carefully when in mourning, but fools focus their thoughts on pleasure.

I turned my thoughts to know, explore, and seek wisdom and an explanation for things, and to know that wickedness is stupidity and folly is madness.

Do not curse the king even in your thoughts,and do not curse a rich person even in your bedroom,for a bird of the sky may carry the message,and a winged creature may report the matter.

Let the conclusion of all of these thoughts be heard: Fear God and obey his commandments, for this is what it means to be human.
