During the rule of the judges, there is another famine (this happens a lot; could it be that the climate just sucked?); Ruth, the Moabite widow of an expat Israelite, returns to Judah with her mother-in-law, as she heard the stories of god feeding his people (a somewhat shaky bet, but then, it *was* a famine) and wants to take care of her (there were 2 sons; both died childless. The other widow went her own way). They end up in Beth-lehem (this place turns up an awful lot in the stories; do you begin to see how it might be quite convenient if, say, a saviour were born there?). Working on the land, gleaning ears of corn (a bit like Tess of the d'Urbervilles, although that at least was an excellent story), she is noticed by Boaz, a distant relative of her husband. He allows her to have her lunch with his people. At home, her mother-in-law instructs her to go to Boaz that night, "uncover his feet and lay thee down". She dutifully obeys; Boaz is pleased at her "kindness" (feel free to fill in the blanks) and rewards her with "six measures of barley", at least slightly better pay for services rendered than the oxen heart the unnamed girl gets in Umberto Eco's Name Of The Rose (another vastly superior book, but then, there are so many). Boaz approaches another, nearer, kinsman of Ruth's husband and instructs him to buy the land of Ruth & her mother-in-law. The man wants to comply, but complicated inheritance legislation makes this somehow impossible so Boaz does it himself, sealing the deal by taking off a shoe (a customary gesture). Buying the land obviously entitles him to Ruth as well (women come with the property, so to speak); the women praise god for "saving" Ruth & providing for her. Boaz quickly "went in unto her" & she gives birth to a son, Obed, who will have at least one very famous grandchild: David (new testament scribes will go to great lengths connecting him to Jesus through the lineage of Joseph… who wasn't even Jesus' biological father. Another exercise in futility).
The whole book only seems to be included to provide some background lineage for King David, but really guys, is this the best you could do?
