Here's your Bible cite:
Matthew 6:5
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.Matthew 6:6
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.Matthew 6:7
But when ye pray, use not vain repetitions, as the heathen [do]: for they think that they shall be heard for their much speaking.
You should be consistent at least.
