5 Which removeth the mountains, and they know not: which overturneth them in his anger.
5 He moves mountains without their knowing it and overturns them in his anger.
5 he who removes mountains, and they know it not, when he overturns them in his anger,
5 He moves mountains before they know what's happened, flips them on their heads on a whim.
5 He removes the mountains, and they do not know When He overturns them in His anger;
5 "Without warning, he moves the mountains, overturning them in his anger.
Matthew Henry's Commentary on Job 9:5
Commentary on Job 9:1-13
(Read Job 9:1-13)
In this answer Job declared that he did not doubt the justice of God, when he denied himself to be a hypocrite; for how should man be just with God? Before him he pleaded guilty of sins more than could be counted; and if God should contend with him in judgment, he could not justify one out of a thousand, of all the thoughts, words, and actions of his life; therefore he deserved worse than all his present sufferings. When Job mentions the wisdom and power of God, he forgets his complaints. We are unfit to judge of God's proceedings, because we know not what he does, or what he designs. God acts with power which no creature can resist. Those who think they have strength enough to help others, will not be able to help themselves against it.
