'Family' in the Bible

Naomi had a close relative of her late husband, a man of considerable wealth from the family of Elimelech. His name was Boaz.

So she went out, proceeded to the field, and gleaned behind the harvesters. And it happened that she came to the portion of land belonging to Boaz, of the family of Elimelech.

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!"
