When it comes to the Book of Ruth, many want to see a common cultural practice underlying the actions which Naomi directed. The reality is that we see no such practice in the Bible – anywhere! (Please search for yourself!) Without other biblical texts to support this conclusion, I must take the text at face value. There is no unique cultural interpretation here. In other words, when a woman bathes, puts on perfume and dons her best dress, and then secretively climbs under the covers with a man who has had his fill of food and wine, I don’t think anyone in any culture would read this in any way but what we all assume.
That being said, the godly character of both Ruth and Boaz is dramatically displayed against the backdrop of chapter 3. Circumstances were far from ideal here, but that did not prevent them from living in a way that should command our respect. We often bemoan the fact that we live in dark days, and are more than willing to complain about the evil of our day. Is today any different than the times of the Judges of Israel? It is during such times that the light of the gospel should shine ever more brightly from the distinctiveness of His people so God will get the glory!
