'Wife' in the Bible

Now it came to pass in the days when the judges ruled, that there was a famine in the land. And a certain man of Bethlehemjudah went to sojourn in the country of Moab, he, and his wife, and his two sons.

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 Bethlehemjudah. And they came into the country of Moab, and continued there.

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 said Boaz, What day thou buyest the field of the hand of Naomi, thou must buy it also of Ruth the Moabitess, the wife of the dead, to raise up the name of the dead upon his inheritance.

Moreover Ruth the Moabitess, the wife of Mahlon, have I purchased to be my wife, to raise up the name of the dead upon his inheritance, that the name of the dead be not cut off from among his brethren, and from the gate of his place: ye are witnesses this day.

So Boaz took Ruth, and she was his wife: and when he went in unto her, the LORD gave her conception, and she bare a son.
