Verses 14, 15. - What then shall I do when God riseth up? Job regards God as the Avenger and Champion of all the oppressed. If he had been harsh and cruel to his dependants, he would have provoked God's anger, and God would assuredly "rise up" one day to punish. What, then, could he (Job) do? What but submit in silence? When he visiteth, what shall I answer him? There could be no valid defence. The slave was still a man, a brother - God's creature, equally with his master. Did not he that made me in the womb make him? and did not one fashion us in the womb? God "hath made of one Mood all nations of men," and all individual me, "to dwell on the face of the earth" (Acts 17:26). All have rights - in a certain sense, equal rights. All are entitled to just treatment, to kind treatment, to merciful treatment. Job is before his age in recognizing the substantial equality of the slave with the freeman, which otherwise was scarcely taught by any until the promulgation of the gospel (see 1 Timothy 6:2; Philemon 1:16).

31:9-15 All the defilements of the life come from a deceived heart. Lust is a fire in the soul: those that indulge it, are said to burn. It consumes all that is good there, and lays the conscience waste. It kindles the fire of God's wrath, which, if not quenched by the blood of Christ, will consume even to eternal destruction. It consumes the body; it consumes the substance. Burning lusts bring burning judgments. Job had a numerous household, and he managed it well. He considered that he had a Master in heaven; and as we are undone if God should be severe with us, we ought to be mild and gentle towards all with whom we have to do.What then shall I do when God riseth up?.... That is, if he had despised and rejected the cause of his servants, or had neglected, or refused to do them justice; he signifies he should be at the utmost loss to know what to do, what excuse to make, or what to say in his own defence, when God should rise up to defend the cause of the injured; either in a way of Providence in this life, or at the great day of judgment in the world to come, when everything will be brought to account, and masters and servants must stand alike before the judgment seat of God, to receive for the things they have done, whether good or evil:

and when he visiteth, what shall I answer him? when he makes a visitation among men, either in this world, even in a fatherly way, visits transgressions, and reproves and corrects for them; had he been guilty of ill usage of his servants, he must have silently submitted to such visitations and chastisements, having nothing to say for himself why he should not be thus dealt with; or in the world to come, in the great day of visitation, when God shall make inquisition for sin, and seek it out, and call to an account for it; and should this be produced against him, even contempt of the cause of his servants, he was sensible he could not answer him for it, nor for anyone sin of a thousand, as no man will be able to do; but must be speechless, unless he has a better righteousness than his own to answer for him in that time to come. This is Job's first reason which deterred him from using his servants ill; another follows.
