And they come unto thee as the people cometh, and they sit before thee as my people, and they hear thy words, but they will not do them: for with their mouth they shew much love, but their heart goeth after their covetousness. As the people cometh - As they are accustomed to come on public days, Sabbaths, etc.
With their mouth they show much love - They respected the prophet, but would not bend themselves to follow his precepts. They loved earthly things, and did not relish those of heaven.
