'Exerted' in the Bible

And the northern I put far off from you, And have driven him unto a land dry and desolate, With his face unto the eastern sea, And his rear unto the western sea, And come up hath his stink, And come up doth his stench, For he hath exerted himself to work.

Do not fear, O land! joy and rejoice, For Jehovah hath exerted Himself to work.
