'Applying' in the Bible

“You shall not profane My holy name [using it to honor an idol, or treating it with irreverence or contempt or as a byword]; but I will be sanctified (set apart as holy) among the Israelites. I am the Lord, who sanctifies and declares you holy,

So that your ear is attentive to [skillful and godly] wisdom,And apply your heart to understanding [seeking it conscientiously and striving for it eagerly];

All this I have seen while applying my mind to every deed that is done under the sun. There is a time in which one man has exercised power over others to their detriment.
