'Wife' in the Bible

Now there came a time of famine while judges were ruling in the land of Israel. A man from Bethlehem of Judah, his wife, and his two sons left to live in the country of Moab.

Boaz continued, "On the very day you buy the field from Naomi, you're also "buying" Ruth the Moabite woman, the wife of her dead husband, so the family name may be continued as an inheritance."

along with Mahlon's wife Ruth the Moabite woman. I will marry her to continue the family name as an inheritance, so that the name of the deceased does not disappear from among his relatives, nor from the public record. You are all witnesses today!"

So Boaz took Ruth to be his wife, and when he had marital relations with her, the LORD made her conceive, and she bore a son.
