Matthew 6:6-8

6But thou, when thou prayest, enter into thy chamber, and having shut thy door, pray to thy Father who is in secret, and thy Father who sees in secret will render [it] to thee.

7But when ye pray, use not vain repetitions, as those who are of the nations: for they think they shall be heard through their much speaking.

8Be not ye therefore like them, for your Father knows of what things ye have need before ye beg [anything] of him.
