Job 33:23

20 He has no desire for food, and his soul is turned away from delicate meat;

21 His flesh is so wasted away, that it may not be seen, and his bones. ...

22 And his soul comes near to the underworld, and his life to the angels of death.

23 If now there may be an angel sent to him, one of the thousands which there are to be between him and God, and to make clear to man what is right for him;

24 And if he has mercy on him, and says, Let him not go down to the underworld, I have given the price for his life:

25 Then his flesh becomes young again, and he comes back to the days of his early strength;

26 He makes his prayer to God, and he has mercy on him; he sees God's face with cries of joy; he gives news of his righteousness to men;
