'Solely' in the Bible

Teach me Your way, O Lord,I will walk and live in Your truth;Direct my heart to fear Your name [with awe-inspired reverence and submissive wonder].

For the Assyrian king has said,“I have done this by the power of my [own] hand and by my wisdom,For I have understanding and skill.I have removed the boundaries of the peoplesAnd have plundered their treasures;Like a bull I have brought down those who sat on thrones.
