The wife of Boaz was Ruth. Ruth was a Moabitess, widowed of one of the son’s of the Jewess, Naomi. Note the scriptures tell us ‘the two shall become one’. The son of Boaz and Ruth was Obed, meaning worship. I tend to see Ruth as a Jewess through her marriage to the Jewish son of Jewess Naomi. So when she and Boaz conceived Obed, Ruth was more thamn just a Moabitess.
that is the mercy of God:
that the Moabite Ruth
the prostitute Rahab
and my wicked self
could all be grafted into His family
