Matthew 7:6-8

6 Give not that which is holy unto the dogs, neither cast ye your pearls before swine, lest they trample them under their feet, and turn again and rend you. 

7 Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you: 

8 For every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened.
