That the hypocrite reign not - All this is done to prevent wicked men from ruling over the people. The remarks of Elihu had had respect much to princes and kings, and he had shown that however great they were, they were in the hands of God, and were wholly at his disposal. He "now" says that the design of his dealings with them was to prevent their oppressing their fellow-men. The general scope of the remarks of Elihu is, that God is the universal Sovereign; that he has all people under his control, and that there are none so powerful as to be able to resist his will. The remark in this verse is thrown in, not as illustrating this general sentiment, but to show what was "in fact" the aim for which he thus interposed - to save people from being oppressed and crushed by those in authority.
Lest the people be ensnared - Hebrew "From their being snarers of the people." He thrusts down the mighty, in order that they may not be left to take the people as wild beasts are taken in the toils. They were disposed to make use of their power to oppress others, but God interposes, and the people are saved. For a fuller view of this verse, see the remarks of Rosenmuller.

That the hypocrite reign not - The Vulgate translates, Who causes a wicked man to reign because of the sins of the people. This was precisely the defense which Hegiage, the oppressive ruler of the Babylonian Irak, under the caliph Abdul Malec, made when he found the people in a state of insurrection. See at the end of the chapter, Job 34:37 (note).

That the (y) hypocrite reign not, lest the people be ensnared.
(y) When tyrants sit in the throne of justice which under pretence of executing justice are hypocrites and oppress the people, it is a sign that God has drawn back his countenance of favour from that place.

That the hypocrite reign not,.... These words seem to be connected with Job 34:24, "he breaketh in pieces mighty men", &c. the whole of Job 34:29 being read in a parenthesis; or with the phrase "he hideth his face"; as God is said to be in the destruction of mighty wicked men, who oppress the poor, and cause their cry to come to God, to prevent the reign of an hypocrite, or however to shorten it. By "an hypocrite" is not meant a common hypocrite in religion, but an hypocrite in politics; who pretends to great humanity and goodness, to a tender care of the people, and a preservation of them in their rights and liberties, and promises to support and establish the constitution, and observe the laws of the nation, with a show of zeal for the religion professed in it. But when he has ascended the throne, and got the power into his hands, he throws off the mask and becomes a tyrant; and men of such a temper, either God does not suffer to ascend the throne, but if they do get on it through artifice and deceit, he suffers them not to continue, but deposes them, and cuts their reign short: and this he does
lest the people be ensnared; be brought into bondage, and lose their rights, privileges, and liberties; or lest they be drawn into sin by their precepts or examples. Some take the sense of the words to be, that God suffers not such to reign, but when he does it is because of the offences or sins of the people; he gives them such kings in his wrath, to punish them for their iniquities.

Ensnared--into sin (1-Kings 12:28, 1-Kings 12:30). Or rather, "enthralled by further oppression," Job 34:26-28.

Reign not - May not continue his tyranny, lest the people be ensnared, lest the people should be longer kept in the the snares of oppression; God doth this to free poor oppressed people from the snares which ungodly men lay for them.
