Matthew 6:5-8 (LSB)
5 “And when you pray, you are not to be like the hypocrites; for they love to stand and pray in the synagogues and on the street corners so that they may be seen by men. Truly I say to you, they have their reward in full.
6 But 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 what is done in secret will reward you.
7 “And when you are praying, do not use meaningless repetition as the Gentiles do, for they suppose that they will be heard for their many words.
8 Therefore, do not be like them; for your Father knows what you need before you ask Him.
