He who rides the horse of greed at a gallop will pull it up at the door of shame (West Africa, Fulani)

The righteousness of the upright shall deliver them: but transgressors shall be taken in their own naughtiness.
The leech that does not let go even when it is filled, dies on the dry land.
Any others out there?
