'Wife' in the Bible

In the days when the judges governed [Israel], there was a famine in the land [of Canaan]. And a certain man of Bethlehem in Judah went to live temporarily in the country of Moab with his wife and his two sons.

I have also acquired Ruth the Moabitess, the widow of Mahlon, to be my wife to restore the name of the deceased to his inheritance, so that the name of the deceased will not be cut off from his brothers or from the gate of his birthplace. 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.
