'Wife' in the Bible

Now there came a time, in the days of the judges, when there was no food in the land. And a certain man went from Beth-lehem-judah, he and his wife and his two sons, to make a living-place in the country of Moab.

And the name of the man was Elimelech, and the name of his wife Naomi, and the name of his two sons Mahlon and Chilion, Ephrathites of Beth-lehem-judah. And they came into the country of Moab, and were there for some time.

And he said, Who are you? And she answering said, I am your servant Ruth: take your servant as wife, for you are a near relation.

Then Boaz said, On the day when you take this field, you will have to take with it Ruth, the Moabitess, the wife of the dead, so that you may keep the name of the dead living in his heritage.

And, further, I have taken Ruth, the Moabitess, who was the wife of Mahlon, to be my wife, to keep the name of the dead man living in his heritage, so that his name may not be cut off from among his countrymen, and from the memory of his town: you are witnesses this day.

So Boaz took Ruth and she became his wife; and he went in to her, and the Lord made her with child and she gave birth to a son.
