53 The origin of Ruth was incest, for she belonged to the tribe of Moab (Ruth 1:4), the fruit of Lot's incestuous union with his daughter (Gen. 19:30-38). Deuteronomy 23:3 forbade the Moabites to enter the assembly of Jehovah, even to the tenth generation. Ruth, however, not only was accepted by the Lord but also became one of the most important ancestors of Christ because she sought God and God's people (Ruth 1:15-17; 2:11-12). Regardless of who we are and what our background is, as long as we have a heart that seeks God and His people, we are in a position to be accepted into the birthright of Christ.
Boaz's mother, Rahab, was a Canaanitess and a prostitute, and his wife, Ruth, was a Moabitess of incestuous origin and a widow. Both were Gentiles and of low class, yet they are associated with Christ. Christ is joined not only to the Jews but also to the Gentiles, even to those of low estate.
