Complete Commentary on the Whole Bible, by Matthew Henry, at sacred-texts.com
(Job 30:1-14) Job's honour is turned into contempt.
(v. 15-31) Job a burden to himself.
Job contrasts his present condition with his former honour and authority. What little cause have men to be ambitious or proud of that which may be so easily lost, and what little confidence is to be put in it! We should not be cast down if we are despised, reviled, and hated by wicked men. We should look to Jesus, who endured the contradiction of sinners.
Job complains a great deal. Harbouring hard thoughts of God was the sin which did, at this time, most easily beset Job. When inward temptations join with outward calamities, the soul is hurried as in a tempest, and is filled with confusion. But woe be to those who really have God for an enemy! Compared with the awful state of ungodly men, what are all outward, or even inward temporal afflictions? There is something with which Job comforts himself, yet it is but a little. He foresees that death will be the end of all his troubles. God's wrath might bring him to death; but his soul would be safe and happy in the world of spirits. If none pity us, yet our God, who corrects, pities us, even as a father pitieth his own children. And let us look more to the things of eternity: then the believer will cease from mourning, and joyfully praise redeeming love.
