Modesty in a Father-in-Law's House
From Tamar Chazal learn that a bride's quiet modesty in her husband's family can bring kings and prophets into the world.
The Gemara asks a simple question. The verse says that Yehudah took Tamar for a woman of the road because she had covered her face. Why should a covered face make him think so? It answers that she had covered her face in her father-in-law's house, so he did not know her when he met her on the road. From here Rav Shmuel bar Nachmani teaches in the name of Rebbi Yonasan that every bride who is modest in the house of her father-in-law merits that kings and prophets come from her. Kings came from Tamar through Dovid. Prophets came too, as Rav Levi received from his fathers: Amotz, the father of Yeshayahu, and Amatzyah, king of Yehudah, were brothers. The quiet conduct of one young woman in a family home carried within it the royal house of Israel.

Tamar's greatness grew in the quiet way she carried herself in her husband's family. Think of your in-laws, or of any family or community that took you in. This week, do one thing that honors them without being asked: call a father-in-law or mother-in-law just to ask how they are, speak of them warmly to your children, or hold back a remark you might have made. Small, unseen respect builds a home that blessing can grow from.
