Job 6:11; Job 16:3; Job 28:3

11 What is my strength, that I should hope ? and what is mine end, that I should prolong my life?
3 Shall vain words have an end? or what emboldeneth thee that thou answerest ?
3 He setteth an end to darkness, and searcheth out all perfection: the stones of darkness, and the shadow of death.
