That the hypocrite reign not, lest the people be ensnared; rather, that an ungodly man reign not, that a people be not a snare. (So Schultens, Professor Lee, and others.) The passage is obscure from its brevity; but this seems to be the best sense.
God withdraws his favour from an ungodly king or from a wicked nation, that the king may cease to injure men by his rule, and the nation cease to be a snare to its neighbours.
