'Two' in the Bible

Now it came about in the days when the judges governed, that there was a famine in the land. And a certain man of Bethlehem in Judah went to sojourn in the land of Moab with 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, Ephrathites of Bethlehem in Judah. Now they entered the land of Moab and remained there.

Then Elimelech, Naomi’s husband, died; and she was left with her two sons.

Then both Mahlon and Chilion also died, and the woman was bereft of her two children and her husband.

So she departed from the place where she was, and her two daughters-in-law with her; and they went on the way to return to the land of Judah.

And Naomi said to her two daughters-in-law, “Go, return each of you to her mother’s house. May the Lord deal kindly with you as you have dealt with the dead and with me.
