John Gill Commentary Ruth 1:5

"And Mahlon and Chilion died both of them; and the woman was left of her two children and of her husband." — Ruth 1:5 (ASV)

And Mahlon and Chilion died also both of them
As well as their father, in the land of Moab, after they had lived with their wives in it about ten years; the Targum is, ``because they transgressed the decree of the Word of the Lord, and joined in affinity with strange people, their days were cut off;'' or shortened:

and the woman was left of her two sons and her husband ;
deprived both of her husband and her sons, which was a great affliction, aggravated by her being in a strange country; many are the afflictions of the righteous.
