Matthew 7:6-10

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.

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

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

Or what man is there of you, whom if his son ask bread, will he give him a stone?

Or if he ask a fish, will he give him a serpent?
