Matthew 6:5-7

5 And when thou prayest, thou shalt not be as the hypocrites are: for they love to pray standing in the synagogues and in the corners of the streets, that they may be seen of men. Verily I say unto you*, They have their reward.

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.
