Sanhedrin 99b. The William Davidson Talmud. Sefaria. Quote: "Timna sought to convert. She came before Abraham, Isaac, and Jacob, and they did not accept her. She went and became a concubine of Eliphaz, son of Esau, and said, referring to herself: It is preferable that she will be a maidservant for this nation, and she will not be a noblewoman for another nation. Ultimately, Amalek, son of Eliphaz, emerged from her, and that tribe afflicted the Jewish people. What is the reason that the Jewish people were punished by suffering at the hand of Amalek? It is due to the fact that they should not have rejected her when she sought to convert. Therefore, the verse is significant."
