The Prophet in the first verse seems to have in view the two tables of the law. God, we know, requires in the law that his people should be holy; and then he teaches the way of living justly and innocently. Hence when the Prophet called Jerusalem a polluted city, he meant briefly to show that the whole worship of God was there corrupted, and that no regard for true religion flourished there; for the Jews thought that they had performed all their duty to God, when they washed away their filth by water. Such was the extremely foolish notion which they entertained: but we know and they ought to have known that the worship of God is spiritual. He afterwards adds, that the city was rapacious, under which term he includes every kind of injustice.
