Matthew 6:5-7

5“When you pray, do not be like the hypocrites; for they love to pray standing in the synagogues and on the street corners, so that they may be seen by others. Amen, I tell you, they have their reward in full!

6But you, when you pray, go into your inner room; and when you have shut your door, pray to your Father who is in secret. And your Father, who sees in secret, shall reward you.

7And when you are praying, do not babble on and on like the pagans; for they think they will be heard because of their many words.
