Ruth 4:12
The comparison of Boaz's household to the house of Perez, the son born to Judah through his encounter with Tamar (herself a woman who had to take bold initiative to secure her rights), establishes a typological connection between Ruth's story and earlier biblical accounts of women who seized their redemption. Tamar's story, like Ruth's, involved a widow taking bold action to claim the protection due to her through kinship law, making this blessing particularly apt. The reference to Perez's importance in the lineage of Judah foreshadows that Ruth's son, born of her union with Boaz, will occupy a similar position of significance.
