When the Law of Moses was being read aloud to the people, they came to the passage that said that no Ammonite or Moabite was ever to be permitted to join God's people.
For about three hours the Law of the Lord their God was read to them, and for the next three hours they confessed their sins and worshiped the Lord their God.
Be sure that the book of the Law is always read in your worship. Study it day and night, and make sure that you obey everything written in it. Then you will be prosperous and successful.
