'Exerciseth' in the Bible

but let him that glorieth glory in this, that he hath understanding, and knoweth me, that I am Jehovah who exerciseth lovingkindness, justice, and righteousness, in the earth: for in these things I delight, saith Jehovah.

And every man that striveth in the games exerciseth self-control in all things. Now they do it to receive a corruptible crown; but we an incorruptible.

And he exerciseth all the power of the first beast before him, and causeth the earth and them which dwell therein to worship the first beast, whose deadly wound was healed.
