Job 16:9

⁷ But now he hath made me weary: thou hast made desolate all my company.

⁸ And thou hast filled me with wrinkles, which is a witness against me: and my leanness rising up in me beareth witness to my face.

He teareth me in his wrath, who hateth me: he gnasheth upon me with his teeth; mine enemy sharpeneth his eyes upon me.

¹⁰ They have gaped upon me with their mouth; they have smitten me upon the cheek reproachfully; they have gathered themselves together against me.

¹¹ God hath delivered me to the ungodly, and turned me over into the hands of the wicked.

Do read the surrounding verses too, because the context often says more than a single verse.
