Then Judah thought, “My sons Er and Onan, they are both dead, and they didn’t have any kids with that woman. So now, my other son Shelah has to marry that woman and have kids with her. That’s the rule in our culture. But if Shelah marries that woman, he might die too, just like Er and Onan.” So Judah got worried, and he didn’t want his son Shelah to marry that woman Tamar. So Judah talked to Tamar, and he tried to trick her. He said to her, “My son Shelah is too young to marry you now. So go back to your father’s house, and live there. Don’t get married to anyone else. Later on, Shelah will grow up, and then you can marry him.” So Tamar went back to her father’s house, and she lived there. Judah’s son Shelah grew up and became a man. But Judah didn’t keep that promise he made to Tamar. He didn’t let her marry his son Shelah.
