Job 5:16 - Matthew Poole's English Annotations on the Holy Bible

So this poor man obtaineth what he in some measure hoped or expected from God, to whom he committed his cause; and other poor men will be encouraged by his example to place their hope in God. Iniquity, i. e. wicked men; the abstract for the concrete, as pride, deceit, injustice, are put for proud, deceitful, and unrighteous men, Jeremiah 13:9 2 Peter 3:13. Stoppeth her mouth, i.e. they are silenced and confounded, being convicted of their own wickedness and folly, and finding that not only the poor are got out of their nets and snares, in which they thought that they had them fast, but also the oppressors themselves are insnared in them; and all this by sudden and unexpected means.
