'Find Satisfaction' in the Bible

And I set my mind to know [practical] wisdom and to discern [the character of] madness and folly [in which men seem to find satisfaction]; I realized that this too is a futile grasping and chasing after the wind.

Out of the suffering of his soul he will see light and find satisfaction. And through his knowledge his servant, the righteous one, will make many righteous, and he will bear their iniquities.
