'Wife' 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.

Moreover, I have acquired Ruth the Moabitess, the widow of Mahlon, to be my wife in order to raise up the name of the deceased on his inheritance, so that the name of the deceased will not be cut off from his brothers or from the court of his birth place; you are witnesses today.”

So Boaz took Ruth, and she became his wife, and he went in to her. And the Lord enabled her to conceive, and she gave birth to a son.
