Matthew 6:5
Jesus teaches people how to pray
5 ‘Also, you must not pray in the way that the hypocrites pray. They like to stand and pray in their meeting places. They like to do it on the corners of the busy streets. Then many people will see them and they will praise them. I tell you this. They have already received their gift from people. God will not give them anything more.
6:5The corners of the streets were places where Jews met to pray. They also prayed in the special buildings. In those places there were a lot of people who could see them when they were praying.
