Definition of "Uzza"

Let them make ſhews of reforming while they will, ſo long as the Church is mounted upon the Prelatical Cart, and not as it ought, between the hands of the Miniſters, it will but ſhate and totter; and he that ſets to his hand, though with a good intent to hinder the ſhogging of it, in this unlawful Waggonry wherein it rides, let him beware it be not fatal to him as it was to Uzza.
