In context
Before · Matthew 6:5–6
5“When you pray, you shall not be as the hypocrites, for they love to stand and pray in the synagogues and in the corners of the streets, that they may be seen by men. Most certainly, I tell you, they have received their reward. 6But you, when you pray, enter into your inner room, and having shut your door, pray to your Father who is in secret; and your Father who sees in secret will reward you openly.
7In praying, don’t use vain repetitions as the Gentiles do; for they think that they will be heard for their much speaking.
