GEN 38:11

11 Then Judah said to his daughter-in-law Tamar, “Return to your father’s house, but do not marry anyone else. When my youngest son Shelah grows up, [he can marry you].” But Judah [really did not want Shelah to marry her, because] he was afraid that then Shelah would die too, just as his older brothers had died. So Tamar [obeyed Judah and] went back to live in her father’s house again.
