John Chrysostom
Upon learning of her mother-in-law's passing and that Judah had gone to Tamnah to shear sheep, Tamar chose to deceive her father-in-law in order to share his bed and conceive children by him. This act was not driven by mere lust but stemmed from a desire to ensure her legacy, as she did not want to be left nameless, without descendants. Yet, within this situation lay divine providence, which allowed her intentions to come to fruition. It is noted that she removed her widow's garments, veiled herself, and concealed her identity, sitting at the city gate. The sacred text adds, “For she saw that Shelah had grown up, and she was not given to him to be his wife," indicating her motivation behind this ruse.
