Luke 11:10-13 King James Version (KJV)
10 For every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened.
11 If a son shall ask bread of any of you that is a father, will he give him a stone? or if he ask a fish, will he for a fish give him a serpent?
12 Or if he shall ask an egg, will he offer him a scorpion?
13 If ye then, being evil, know how to give good gifts unto your children: how much more shall your heavenly Father give the Holy Spirit to them that ask him?
