Matthew 6:6-7

King James Version

⁶ But thou, when thou prayest, enter into thy closet, and when thou hast shut thy door, pray to thy Father which is in secret; and thy Father which seeth in secret shall reward thee openly.

⁷ But when ye pray, use not vain repetitions, as the heathen do: for they think that they shall be heard for their much speaking.
