Then Judah said to his daughter-in-law Tamar, "Live as a widow in your father's house until my son Shelah grows up." For he thought, "He may die too, like his brothers." So Tamar went to live in her father's house.

Genesis 38:14
she removed her widow's garments, covered her face with a veil to disguise herself, and sat at the entrance to Enaim, which is on the way to Timnah. For she saw that although Shelah had grown up, she had not been given to him as a wife.

Ruth 1:11
But Naomi replied, "Return home, my daughters. Why would you go with me? Are there still sons in my womb to become your husbands?

Ruth 1:12
Return home, my daughters. Go on, for I am too old to have another husband. Even if I thought there was hope for me to have a husband tonight and to bear sons,

Ruth 1:13
would you wait for them to grow up? Would you refrain from having husbands? No, my daughters, it grieves me very much for your sakes that the hand of the LORD has gone out against me."

Then said Judah to Tamar his daughter in law, Remain a widow at your father's house, till Shelah my son be grown: for he said, Lest peradventure he die also, as his brothers did. And Tamar went and dwelled in her father's house.
