There are various instances in the Bible of people needing to leave the place where they had been staying and moving somewhere else. Although there were various reasons for this, one of the main ones was having to leave a country because of a famine.
In the book of Ruth, one of the books of the Old Testament, there is the story of Elimelech who, with his wife Naomi and his two sons, left their home in Bethlehem as a result of a famine. Moab became their new home. However sadly in time Elimelech died.
His two sons got married but unfortunately some ten years later, they too passed way. This left Naomi with her two daughters-in-law - Orpah and Ruth. When Naomi learned that there had been a good harvest in Bethlehem she decided that she wanted to return home. While Oraph was eventually persuaded to stay in Moab, Ruth decided that she was going to remain with her mother-in-law, despite the fact that it meant leaving her friends and the rest of her family behind.
It was a brave and selfless thing to do. While in Bethlehem, Ruth provided for them both by going into one of the fields each day and collecting up the corn that was left by the harvest workers, as was permitted at the time. The owner of the field was a rich man called Boaz who, unknown to her, was a relative of Naomi’s. Boaz was impressed by Ruth’s kindness and loyalty. The two of them eventually got married and were delighted when their son Obed was born. He was the grandfather of the famous King David. However this positive outcome only came about because Ruth was prepared to make sacrifices to ensure that her mother-in-law was properly looked after.
