This also were an iniquity to be punished by the judges: for I should have lied to God that is above.

It also is a judicial iniquity, For I had lied to God above.

That would have been another sin to be rewarded with punishment by the judges; for I would have been false to God on high.

This also were an iniquity to be punished by the judqe - Note Job 31:11. Among the Hebrews idolatry was an offence punishable by death by stoning; Deuteronomy 17:2-7. It is possible, also, that this might have been elsewhere in the patriarchal times a crime punishable in this manner. At all events, Job regarded it as a heinous offence, and one of which the magistrate ought to take cognizance.
For I should have denied the God that is above - The worship of the heavenly bodies would have been in fact the denial of the existence of any Superior Being. This, in fact, always occurs, for idolaters have no knowledge of the true God.

For I should have denied the God that is above - Had I paid Divine adoration to them, I should have thereby denied the God that made them.

This also [were] an iniquity [to be punished by] the judge: for I should have denied the God [that is] (t) above.
(t) By putting confidence in anything but in him alone.

This also were an iniquity to be punished by the judge,.... As well as adultery, Job 31:11; by the civil magistrates and judges of the earth, who are God's vicegerents, and therefore it behooves them to take cognizance of such an iniquity, and to punish for it, which affects in so peculiar a manner the honour and worship of the true God; this by the law of Moses was punished by stoning to death, Deuteronomy 13:9; however this will be taken notice of and punished by God the Judge of all, whose law is broken hereby, and who will visit this iniquity more especially on those who commit it, and their posterity after them. Idolaters of every sort shall have their part and portion in the lake which burns with fire and brimstone, Exodus 20:3; the consideration of its being such a heinous sin, and so deserving of punishment, deterred Job from it; the Targum paraphrases it, a most amazing iniquity, it being, as follows, a denial of the true God:
for I should have denied the God that is above; that is, had he worshipped the sun and moon secretly or openly; for, as the atheist denies him in words, the idolater denies him in facts, worshipping the creature besides the Creator, and giving his glory to another, and his praise to idols; which is a virtual denial of him, even of him who is above the sun and moon in place, being higher than the heavens; and in nature, excellency, and glory, being the Creator of them, and they his creatures; and in power and authority, who commands the sun, and it rises not, and has appointed the moon for seasons, Job 9:7.

The Mosaic law embodied subsequently the feeling of the godly from the earliest times against idolatry, as deserving judicial penalties: being treason against the Supreme King (Deuteronomy 13:9; Deuteronomy 17:2-7; Ezekiel 8:14-18). This passage therefore does not prove Job to have been subsequent to Moses.

The judge - The civil magistrate; who being advanced and protected by God, is obliged to maintain and vindicate his honour, and consequently to punish idolatry. Denied God - Not directly but by consequence, because this was to rob God of his prerogative, by giving to the creature, that worship which is peculiar to God.
