In the Parable of the Sower (Matthew 13:1-23), the seed that falls on rocky ground represents individuals who:

A Hear the word and immediately accept it with joy, but fall away when trouble or persecution comes. B Do not understand the word, and the evil one snatches away what was sown in their hearts. C Hear the word, but the worries of this life and the deceitfulness of wealth choke it, making it unfruitful. D Hear the word and understand it, producing a crop, yielding a hundred, sixty or thirty times what was sown.
