In the days when the judges ruled there was a famine in the land, and a man of Bethlehem in Judah went to sojourn in the country of Moab, he and his wife and his two sons. The name of the man was Elimelech and the name of his wife Naomi, and the names of his two sons were Mahlon and Chilion. They were Ephrathites from Bethlehem in Judah. They went into the country of Moab and remained there. But Elimelech, the husband of Naomi, died, and she was left with her two sons. These took Moabite wives; the name of the one was Orpah and the name of the other Ruth. They lived there about ten years, and both Mahlon and Chilion died, so that the woman was left without her two sons and her husband. (Ruth 1:1-5)
Elimelech's care to provide for his family, was not to be blamed; but his removal into the country of Moab could not be justified. And the removal ended in the wasting of his family.
It is folly to think of escaping that cross, which, being laid in our way, we ought to take up. Changing our place seldom is mending it. Those who bring young people into bad acquaintance and take them out of the way of public ordinances, though they may think them well-principled, and armed against temptation, know not what the end will be.
It does not appear that the women the sons of Elimelech married, were proselyted to the Jewish religion. Earthly trials or enjoyments are of short continuance.
Death continually removes those of every age and situation and mars all our outward comforts: we cannot too strongly prefer those advantages which shall last forever.
From Matthew Henry's Concise Commentary on the Whole Bible
