Dhammapada verses 70 and 71

70. Month after month a fool may eat his food with the tip of a blade of grass, but he still is not worth a sixteenth part of the those who have comprehended the Truth.

71. Truly, an evil deed committed does not immediately bear fruit, like milk that does not turn sour all at once. But smoldering, it follows the fool like fire covered by ashes.
