'Exercised' in the Bible

And I gave my heart to seek and search out by wisdom concerning all things that are done under heaven: this sore travail hath God given to the sons of man to be exercised therewith.

I have seen the travail, which God hath given to the sons of men to be exercised in it.

The people of the land have used oppression, and exercised robbery, and have vexed the poor and needy: yea, they have oppressed the stranger wrongfully.
