'Married' in the Bible

Each of her sons married Moabite women: one named Orpah and the other named Ruth. After they lived there about ten years,

Go back home, my daughters! For I am too old to get married again. Even if I thought that there was hope that I could get married tonight and conceive sons,

So Boaz married Ruth and had sexual relations with her. The Lord enabled her to conceive and she gave birth to a son.
