An interesting fact about the book of Ruth: it is read in its entirety during the Feast of Pentecost or Shavuot. This celebration traditionally occurred 50 days after Passover, and it is reminder to thank God for His harvest blessing.
Just to be clear about Moab, a quote from the Kelly Minter Ruth study:
"Understanding the history of Moab and their relationship with Israel changes the tone of Elimelech and Naomi's journey. It's not like they were Americans heading to Canada. This was an enemy of Israel, a nation the Lord had historically commanded His children not be be in relationship with." (Week 1, Day 1, pg 12)
