Job 12:16 - Matthew Poole's English Annotations on the Holy Bible

He doth the things here mentioned in the foregoing and succeeding verses, and that both powerfully, so as no creature can resist and hinder him, and wisely, so as none can prevent and overreach him. The same thing he had said before, Job 12:13, but he repeats it here to prepare the way for the following events, which are eminent instances both of his power and wisdom. Are his, i.e. from or by him, and wholly subject to his disposal. That one man deceiveth another, and that the other is deceived by him, either in Divine or civil and worldly things, (which seem to be principally intended here, by comparing the following verses,) this is from God, and by the conduct of his wise and powerful providence. God giveth to the deceiver more wit, and knowledge, and art, and withal opportunity, and all favourable circumstances for his deceit. He also gives less understanding to the deceived, and withdraws from him, either wholly or in part, that common light of discretion which is his free gift; and he may justly give, or take away, as he pleaseth, and leaves him to his own ignorance and error, pride and self-conceit, and to all those prejudices, passions, and lusts which commonly corrupt men's minds, and to the power and crafts of Satan, that grand deceiver. He governs the deceiver, and sets bounds to his deceits, to whom, and when, and how far they shall extend; as is manifest from Deuteronomy 13:1 1 Kings 22:20 Isaiah 19:14 Ezekiel 14:9 Matthew 24:24 2 Thessalonians 2:11 Revelation 20:3,8. He also overrules all this to his own glory, and the accomplishment of his righteous designs of trying the good, and punishing wicked men, by giving them up to believe lies. Yet God is not the cause or author of any error or sin, but only the wise and holy governor and disposer of it.
