Withdraw thine hand far from me: and let not thy dread make me afraid.
(Note, Job 9:34; Psalms 39:10, "Remove thy stroke away from me: I am consumed by the blow of thine hand"). The "two things" (Job 13:20) which Job requests are:
(1) That God will withdraw His heavily pressing hand from him - i:e., remove his disease;
(2) That God will not overwhelm him by His terrible presence, as He usually does those before whom He appears visibly. So Job will not shrink from meeting Him, to try his cause before Him face to face (Job 13:22).
