Yet the children of thy people say,.... "Not my people"; for surely the children of God could never say what follows; and one would think that even no man could say it, after so much had been said by the Lord concerning the righteous and the wicked, and his dealings with them, which must appear to be just and right, good and gracious; and yet such were the atheism, the perverseness and peevishness of these people, they went on to say as they had done before:the way of the Lord is not equal: is not according to the rules of justice and equity.
The Targum is,"the ways of the goodness of the Lord are not made plain (or exposed) unto us.'
