Proverbs 27:20 - Matthew Poole's English Annotations on the Holy Bible

Hell and destruction are never full; the grave devours all the bodies which are put into it, and is always ready to receive and devour more and more without end. The eyes, i.e. the desires, which work and discover themselves by the eyes, 1 John 2:16, and other senses; for otherwise the eyes in themselves are neither capable of satisfaction nor of dissatisfaction.
