'Thinks' in the Bible

But David vowed again, saying “Your father certainly knows that I have found favor in your sight, and he has said, ‘Do not let Jonathan know this, or he will be worried.’ But truly as the Lord lives and as your soul lives, there is hardly a step between me and death.”

“But a hollow (empty-headed) man will become intelligent and wise[Only] when the colt of a wild donkey is born as a man.

His ways prosper at all times;Your judgments [Lord] are on high, out of his sight [so he never thinks about them];As for all his enemies, he sneers at them.

He says to himself, “I will not be moved;For throughout all generations I will not be in adversity [for nothing bad will happen to me].”

He says to himself, “God has [quite] forgotten;He has hidden His face; He will never see my deed.”

He who walks with integrity and strength of character, and works righteousness,And speaks and holds truth in his heart.

For as he thinks in his heart, so is he [in behavior—one who manipulates].He says to you, “Eat and drink,”Yet his heart is not with you [but it is begrudging the cost].

and I saw all the work of God, I concluded that man cannot discover the work that is done under the sun. Even though man may labor in seeking, he will not discover; and [more than that], though a wise man thinks and claims he knows, he will not be able to find it out.

They say “To whom would He teach knowledge?And to whom would He explain the message?Those just weaned from milk?Those just taken from the breast?

“Woe (judgment is coming) to him who obtains wicked gain for his house [and thinks by so doing]To set his nest on high,That he may be rescued from the hand of evil.
