'Mind' in the Bible

I applied my mind to seek and to search by wisdom all that is done under the heavens. It [is] a grievous task God has given to {humans}.

I also {explored} {the effects of indulging my flesh} with wine. My mind guiding me with wisdom, {I investigated} folly so that I might discover what [is] good under heaven for {humans} to do {during the days of their lives}.

I set my mind to try to seek wisdom and the plan, and to know that wickedness [is] foolishness and that folly [is] delusion.

Whoever obeys [his] command will not suffer disaster. The wise mind knows the [proper] time and the right [procedure].

I applied my mind to know wisdom and to understand the business that is done on earth--how neither day nor night one's eyes see sleep.
