How can that be when Boaz wasn't allowed to marry a moabite?

Boaz was indeed a prominent figure from Bethlehem who married Ruth, a Moabite woman, which might seem contradictory to the Israelite prohibition against Moabite intermarriage. However, Ruth's story emphasizes her loyalty and conversion to the Israelite faith, making her integration into the community acceptable. Additionally, the laws surrounding intermarriage were more about preserving the cultural identity of the Israelites rather than an absolute prohibition against all Moabites. Boaz, being a relative of Ruth through her deceased husband, also fulfilled the role of a kinsman-redeemer, which allowed for their union.
